Whether you want to bump an ogre up a few levels or turn it into an elite berserker, this section gives you the tools you need to tinker with monsters. You’ll also find rules for adding a class to a monster, mining the Player’s Handbook for combat powers.
You can use several methods to adjust an existing monster: change its level, give it equipment, alter its appearance and behavior, and apply a template. Each of these approaches is discussed below.
Increasing or Decreasing Level
Boosting a monster’s level is easy. Just increase its attack rolls, defenses, and AC by 1 for every level you add. For every two levels, increase the damage it deals with its attacks by 1. The monster also gains extra hit points at each level, based on its role (see the “Monster Statistics by Role” table on page 184 of the Dungeon Master's Guide).
Decreasing a monster’s level works like increasing it, but in reverse. For each level down, reduce the creature’s attack rolls, defenses, and AC by 1 and drop its hit points based on its role. For every two levels, also reduce its damage by 1.
This process works best for adjusting a monster’s level up to five higher or lower. Beyond that, the monster changes so much that you’d do better to start with another creature of the desired role and level range.
Adding Equipment
You can add equipment to a monster to make it a little more challenging, or to put treasure into the characters’ hands. Equipment shouldn’t be random but should serve some purpose in the design of an encounter. Make sure to include any such items as part of the overall treasure you’re giving out for the adventure (see “Treasure” on page 124 of the Dungeon Master's Guide).
Armor: When you add armor to a monster, you first need to determine if the armor is good enough to improve the monster’s AC. Start with the monster’s effective armor bonus—a measure of how much of the creature’s AC comes from its armor or from its thick hide. This number is equal to its AC minus 10 minus the higher of its Dexterity or Intelligence ability modifiers. Do not include the Dexterity or Intelligence modifier if the creature wears heavy armor. Subtract the effective armor bonus from the creature’s AC, and then add the bonus from its new armor. If the creature moved from heavy to light armor, you can also add the higher of its Dexterity or Intelligence ability modifier to its AC.
If the creature’s statistics block does not mention any worn armor, use the higher of its original AC or its new AC after adding armor. Most creatures have naturally thick hides that provide an armor bonus to AC. If the armor a creature wears is not as good as its natural armor, it uses the AC bonus provided by its natural armor. Worn armor, such as a suit of chainmail, and natural armor, such as an insect’s carapace or a dragon’s thick scales, do not stack.
For example, an ogre savage normally has an Armor Class of 19 (it’s assumed to be wearing crude hide armor). Its effective armor bonus is +5 (19 – 10 – 4 [Dex]). Giving the ogre chainmail instead would improve its AC by 1 to 20, since the armor’s +6 bonus is 1 higher than this number.
Magic Items: A monster equipped with magic items can use the powers those items grant.
Enhancement Bonuses: A monster benefits from an enhancement bonus to attack rolls, defenses, or AC only if that bonus is higher than its magic threshold, as shown on the table below.
A monster’s magic threshold is an abstract representation of its equipment, power, and general effectiveness against characters of its level. If you give the monster a magic item that grants a bonus to attack rolls and damage rolls or to defenses, subtract the magic threshold from that bonus before you apply it. For example, if you give that 8th-level ogre savage a +2 magic greatclub, you add only a +1 bonus to its attack rolls and damage rolls, since its magic threshold is +1.
Monster Level Magic Threshold
1st–5th +0
6th–10th +1
11th–15th +2
16th–20th +3
21st–25th +4
26th–30th +5
Remember that a monster’s game statistics are set to be appropriate for its level. Thus, altering a monster’s attack, defense, or damage values is a lot like changing its level (see above). Avoid the temptation simply to give all your monsters better armor and weapons. Giving all your ogre savages plate armor and +3 greatswords may seem like a reasonable change, but now they have the attack, damage, and defense numbers of a higher-level monster—which makes them a tougher challenge than other 8th-level brutes.
If you want to give a monster equipment that changes its attack, defense, or damage values by more than a point or so, consider also making those alterations as part of changing its level. For example, those ogre savages in plate armor and wielding +3 greatswords have AC, attack rolls, and damage rolls three points higher than normal. That’s pretty close to what a monster three levels higher would have (+3 to all defenses, +3 to attack rolls, and +1 damage), so you might as well make those ogre savages into 11th-level monsters and give them the extra hit points to go along with their other benefits.
Cosmetic Changes
The characters are delving into the jungle-covered ruins of an ancient city now haunted by the yuan-ti. There they discover strange arboreal humanoids with long arms that swoop into battle on the backs of giant wasps. What are these mysterious beings?
This technique is useful for keeping players on their toes even when they know the Monster Manual backward and forward. Use the statistics of a given monster but completely alter its appearance when you describe it to the players. You can make minor changes to its powers as well, altering damage types or changing details of weapons (lashing tentacles become a whipping tail, for example).
Templates
A template is like a recipe for changing a monster. Each template provides instructions for modifying hit points and defenses, and adds a number of powers and abilities. Simply pick a monster and a template, follow the directions, and you’re ready to go.
This section provides more than a dozen templates for customizing monsters. Functional templates adapt a monster to a given purpose in an adventure. You can also add a functional template to a nonplayer character. See “Creating NPCs” on page 186 of the Dungeon Master's Guide for more information. Class templates allow you to add features of a specific character class to a monster.
Multiple Templates: Each of these templates is intended for use by itself, making a monster into an elite opponent. However, you can turn a standard monster into a solo creature by adding two templates. Follow the process for adding each template, one at a time, but add just one template’s hit point bonus (your choice which). Then double the creature’s total hit points. Increase the monster’s saving throw bonus to +5.
You can also advance an elite monster to a solo one by adding a template, then doubling its hit points and adjusting its saving throw as above.
This method is quick and easy, but it carries some risks. For example, the adjusted monster’s hit points might be lower than those of a typical solo monster of its level and role. Once you’ve finished the process, be sure to “reality check” the monster by comparing its statistics and abilities to others of similar power.
How to Read a Template
A template lists changes to a monster’s statistics and grants it some new powers and abilities. In general, if a template does not alter a certain statistic, that entry does not appear in the list.
Each template notes any prerequisites for adding it to a monster. Some can be added to any creature, while others work only with particular types or at certain adventuring tiers.
The modified monster retains all its normal powers and abilities except those that overlap or conflict with those bestowed by the template. Every template begins with a brief descriptive passage that explains the essential nature of the template, followed by a paragraph that tells you what types of creatures or classes the template can be applied to.
Prerequisite: This entry appears if the monster must meet certain requirements to gain the template, such as a specific type or a minimum level. The remaining information is presented in monster stat block form, for easy insertion into the monster’s existing statistics.
Role: The monster’s combat role appears in the upper right corner of the stat block header.
Type and Keyword: The left-hand entry of the second line of the stat block header states this information. If the template adds a keyword to the monster, such as undead, it is included here. The monster retains any previous keywords.
Senses: Add the given abilities to the monster’s Senses entry.
Defenses: Adjust the monster’s AC and other defenses as described in this entry.
Immune/Resist/Vulnerable: Add the stated entries and values. If the monster already has one or more of these abilities, use the more beneficial value.
Saving Throws +2: All elite monsters have a +2 bonus to saving throws.
Action Point 1: All elite monsters have 1 action point.
Hit Points: Add the stated number of hit points for the monster’s new role, and then also add its Constitution score to the new hit point total.
Powers: Add the stated powers to the monster’s stat block, calculating attack and damage numbers. The level of an attack power usually depends on the monster’s level and is expressed as “Level + n,” where “Level” is the monster’s level and n is a number you add to that value. Damage is adjusted by the modifier for a given ability score, just as with characters’ attack powers.
Here are two sample templates, the lich and the vampire lord:
Lich
Liches are evil arcane masterminds that pursue the path of undeath to achieve immortality. They are cold, scheming creatures who hunger for ever-greater power, long-forgotten knowledge, and the most terrible of arcane secrets.
Some liches know a ritual that sustains them beyond destruction by tying their essence to a phylactery. When a lich who has performed this ritual is reduced to 0 hit points, its body and possessions crumble into dust, but it is not destroyed. It reappears (along with its possessions) in 1d10 days within 1 square of its phylactery, unless the phylactery is also found and destroyed.
“Lich” is a template you can add to any intelligent creature of 11th level or higher. It best complements an arcane NPC, such as a wizard or warlock, or a monster with arcane powers, such as a beholder or oni. Other highly intelligent creatures might also become liches; for example, mind flayers, who draw on psionic power.
Prerequisite: Level 11, Intelligence 13

Necrotic Master
The lich can convert any attack power it has to necrotic.
Change a power’s energy keyword to necrotic, or add necrotic energy to an attack power that doesn’t normally deal energy damage. 
Vampire Lord
Vampire lords are powerful and dangerous undead villains. Some are former spawn freed by their creators’ deaths, others mortals chosen to receive the “gift” of vampiric immortality. They can create armies of dominated vampire spawn or pass on their powers to chosen mortals.
“Vampire lord” is a template you can apply to any humanoid creature of 11th level or higher. Vampire lords retain their living appearance, although they are paler and their canines somewhat more pronounced, and they are wholly evil.

Excerpts: Tiers of Play
The Heroic Tier
From the PH: In the heroic tier, your character is already a hero, set apart from the common people by your natural talents, learned skills, and some hint of a greater destiny that lies before you. Your capabilities are largely determined by your choice of character class and to a lesser extent by your race. You move around on foot or on a relatively mundane mount such as a horse. In combat, you might make mighty leaps or incredible climbs, but you’re still basically earthbound. The fate of a village might hang on the success or failure of your adventures, to say nothing of the risk to your own life.
From the DMG: Even 1st-level characters are heroes, set apart from the common people by natural characteristics, learned skills, and some hint of a greater destiny that lies before them.
At the start of their careers, characters rely on their own abilities and powers, and they wield mundane gear. They acquire magic items quickly, though, and might even fill their available item slots by 10th level. In combat, they can make mighty leaps or climb incredibly fast, but they’re still basically earthbound and generally remain visible. Since they rely on healing surges to regain lost hit points, heroic tier characters are likely to take an extended rest when surges get dangerously low. However, toward the upper end of the tier, even death is a surmountable obstacle because of the Raise Dead ritual.
Adventures: The fate of a village might hang on the success or failure of heroic tier adventurers, to say nothing of the characters’ own lives. Heroic characters navigate dangerous terrain and explore haunted crypts, where they can expect to fight savage orcs, ferocious wolves, giant spiders, evil cultists, bloodthirsty ghouls, and shadarkai assassins. If they face a dragon, it’s a young one that might still be searching for a lair and has not yet found its place in the world—in other words, much like themselves.
The Paragon Tier
From the PH: In the paragon tier, your character is a shining example of heroism, set well apart from the masses. Your class still largely determines your capabilities. In addition, you gain extra abilities in your specialty: your paragon path. When you reach 11th level, you choose a path of specialization, a course that defines who you are within a certain narrow range of criteria. You are able to travel more quickly from place to place, perhaps on a hippogriff mount or using a spell to grant your party flight. In combat, you might fly or even teleport short distances. Death becomes a surmountable obstacle, and the fate of a nation or even the world might hang in the balance as you undertake momentous quests.
From the DMG: By 11th level, characters are shining examples of courage and determination—true paragons in the world, set well apart from the masses.
Paragon tier adventurers are a lot more versatile than they were at lower levels, and they can find just the right tool for a given challenge. They can spend action points to gain additional effects, are able to use magic rings, and can sometimes regain limited powers they’ve expended. In combat, they exploit short-range flight and teleportation, making difficult terrain less important, and might be able to turn invisible or resist specific damage types. They also have ways to regain hit points beyond healing surges, including regeneration, so they can complete more encounters between extended rests. On the other hand, monsters at the paragon tier have more ways to thwart these new capabilities, including their own flight, damage resistance, and blindsight.
Rituals at the paragon tier begin to give characters magical ways to gather information and overcome obstacles. Divination rituals such as Consult Oracle grant access to knowledge they might otherwise not have, while View Object can make some kinds of mysteries obsolete. Exploration rituals such as Passwall and Shadow Walk let a party bypass solid barriers and quickly travel long distances.
Adventures: The fate of a nation or even the world might depend on momentous quests that such characters undertake. Paragon-level adventurers explore uncharted regions and delve long-forgotten dungeons, where they confront savage giants, ferocious hydras, fearless golems, evil yuan-ti, bloodthirsty vampires, crafty mind flayers, and drow assassins. They might face a powerful adult dragon that has established a lair and a role in the world.
The Epic Tier
From the PH: In the epic tier, your character’s capabilities are truly superheroic. Your class still determines most of your abilities, but your most dramatic powers come from your choice of epic destiny, which you select at 21st level. You travel across nations in the blink of an eye, and your whole party might take to the air in combat. The success or failure of your adventures has far-reaching consequences, possibly determining the fate of millions in this world and even planes beyond.
From the DMG: By 21st level, characters have truly superheroic capabilities, and their deeds and adventures are the stuff of legend. Ordinary people can hardly dream of such heights of power. Epic adventurers have even more ways to recover expended powers, more ways to heal damage without relying on healing surges, and more powers overall from magic items and epic destinies. In combat, flight and teleportation are routine, as well as extraordinary feats of climbing and jumping. Terrain in general is less important, unless it blocks extraordinary forms of travel. Invisibility is common. Such characters can last through many encounters before resting and can even return from death in the middle of a fight. Furthermore, epic destinies break the rules in dramatic ways.
At the epic tier, rituals include more and better kinds of divination, including the ability to spy on distant beings with Observe Creature. Epic characters can use True Portal to transport themselves instantly anywhere in the world.
Adventures: Epic adventures have far-reaching consequences, possibly determining the fate of millions—in the natural world and even places beyond. Epic characters traverse otherworldly realms and explore never-before-seen caverns of wonder, where they fight savage balor demons, abominations such as the ferocious tarrasque, mind flayer masterminds, terrible archdevils, bloodthirsty lich archmages, and even the gods themselves. The dragons they encounter are ancient wyrms of truly earth-shaking power, whose sleep troubles kingdoms and whose waking threatens existence.
Starting at Higher Level
Sometimes you don’t want to start characters at 1st level. A paragon- or epic-tier game might be more to your taste. Maybe your DM wants to run a published adventure that requires higher-level characters, or you want to try a one-shot that pits 30th-level characters against Orcus. Whatever the reason, at some point you’ll need to create higher-level characters. This process isn’t much harder than making a 1st-level character. The steps for creating a D&D character above 1st level are almost the same as those ones outlined in Chapter 2 of the Player’s Handbook for a new character.
1. Choose Race. Remember that some racial traits improve at higher levels.
2. Choose Class. If your level is 11th or higher, choose a paragon path appropriate to your class. At 21st level or higher, you’ll also need to choose an epic destiny.
3. Determine Ability Scores. Generate scores as for a 1st-level character, applying racial modifiers. Then increase those scores as shown on the Character Advancement table in the Player’s Handbook, with increases at 4th level, 8th level, 11th, 14th, and so on. (You can also use the NPC Ability Scores table on page 187 of the Dungeon Master’s Guide.)
4. Choose Skills. Make sure you meet skill prerequisites for a paragon path or epic destiny, if applicable.
5. Select Feats. You generally don’t have to worry about the level at which you gained a particular feat, since retraining allows you to have the feats you want at any given level. Do watch out for paragon and epic feats, though. For example, a 14th-level character can’t have more than seven paragon feats (those gained at 11th, 12th, and 14th level, as well as up to four retrained feats).
6. Choose Powers. You know two at-will powers from your class; remember to increase damage if your level is 21st or higher. The Powers by Class Level table summarizes the number and levels of powers you have in the other categories. These totals are not cumulative. The table assumes that you replace your lowest-level powers with those at higher levels, but you can keep lower-level ones if you wish.

E: Power from your epic destiny.
7. Choose Equipment and Magic Items. Mundane equipment is much less important for higher level characters than it is when you’re starting out. Choose whatever standard adventuring gear you want from the tables in the Player’s Handbook. For magic items, choose one item of your level +1, one item of your level, and one item of your level –1. In addition, you have gold pieces equal to the value of one magic item of your level –1. You can spend this money on rituals, potions, or other magic items, or save it for later.
8. Fill in the Numbers. After noting the bonuses you gain from feats and magic items (as well as your increased level), calculate your hit points, Armor Class, defenses, initiative, base attack bonuses and damage bonuses, and skill modifiers. The Quick Hit Points table provides a formula for hit points by class.
Quick Hit Points

Cleric (level × 5) + 7 + Constitution score
Fighter (level × 6) + 9 + Constitution score
Paladin (level × 6) + 9 + Constitution score
Ranger (level × 5) + 7 + Constitution score
Rogue (level × 5) + 7 + Constitution score
Warlock (level × 5) + 7 + Constitution score
Warlord (level × 5) + 7 + Constitution score
Wizard (level × 4) + 6 + Constitution score
9. Roleplaying Character Details. Flesh out your character, using the suggestions in Chapter 2 of the Player’s Handbook or your own ideas.

Excerpts: Devils of 4th Edition
Malevolent and corrupt, devils are the rebellious servants of the gods now living in the Nine Hells, one of the darkest dominions on the Astral Sea. Devils come in many varieties, from the sly imp to the mighty archdevils known as the Lords of the Nine, each a ruler of one of the Nine Hells. The greatest of these infernal lords is the god Asmodeus, prince of Nessus, the ninth hell. Long ago, Asmodeus was a powerful divine servant who chose to rebel against the god he served. At the head of an army of like-minded creatures, Asmodeus slew his divine master. For their betrayal, he and his followers were cursed with monstrous forms and imprisoned within the fuming ruin of the murdered god’s dominion.
Devils can leave the Nine Hells, but it is very difficult for them to do so. They can be sent forth by mighty archdevils through costly infernal magic, or travel through rare and well-hidden magical portals (usually only a few at a time when conditions are right). However, most devils outside of the Nine Hells have been brought to the natural world by evil mortals employing dark rituals.
Devils lust for the souls of mortals; each mortal spirit devils enslave undermines the gods’ sway over mortalkind and adds to the Nine Hells’ power. Devils torment and consume captured souls to fuel the mightiest of their infernal works, including evil constructs and terrible invocations. Devils compete fiercely to gather souls in order to earn favor and status within the infernal order, but they all work together toward the common goal of gathering souls for the Nine Hells.
Some devils seek to drive mortals into surrendering their souls through tyranny, despair, or terror; some seek to destroy the servants of good-aligned gods and tear down their works; and still others are tempters and deceivers who inflame mortal ambition, desire, greed, or pride.
Long ago, Asmodeus and his vassals forged dark pacts with various evil deities. Devils are therefore commonly found serving Bane, Gruumsh, Tiamat, Torog, and Vecna. Devils carefully honor their bargains—but they are extremely good at giving reckless mortals exactly what they ask for, and few of those who bargain with devils escape the final payment.
A Primer to the Nine Hells
The Nine Hells form a single dominion on the Astral Sea. Black smoke surrounds them, and beyond this choking veil broods a great, volcanic world whose surface is a blasted plain of ash and jagged stone. This is Avernus, the first of the Nine Hells, where embers rain down from a sunless sky and iron fortresses rise up between rivers of magma. Astral vessels approaching too closely find themselves plummeting through the skies of Avernus rather than sailing in the Astral Sea, landing in the Nine Hells with a great fiery impact. A helmsman of great skill can sometimes negotiate the passage and alight on the ashen plain safely, but the only sure way to avoid fiery disaster is to find the astral influence of the River Styx and follow it down through the basalt cliffs. The Styx cuts a jagged course across Avernus and eventually plunges down into the lower Hells—each one a tremendous continent-sized cavern within the roiling world.
Avernus, the first Hell, forms the surface of this terrible dominion. It’s a volcanic domain strewn with the blood and wreckage of a million battles. Fireballs plunge from the smoke-filled sky. The archdevil Bel, a military genius, protects and rules Avernus from a towering iron citadel.
A great iron gate in a mountainside of Avernus leads to Dis, the second Hell. Dis is an iron-walled city that lies within a vast cavern, sprawling unevenly amid the cavern’s jagged, mountainous floor. Dispater, the ruler of this Hell, is famous as the most cautious and calculating of the archdevils.
The cavern of Dis gradually descends and broadens into the great, low, brooding vault of Minauros, the Third Hell. A constant oily rain pelts down from the ceiling, and the black soil of Minauros is a vast series of mud flats, swamps, and mires, some heated into bubbling, stinking mud volcanoes by the heat rising from below. The serpentine and supremely boastful archdevil Mammon rules here.
Phlegethos, the fourth Hell, lies far below its predecessors. Dank steps cut into the stinking fumaroles of Minauros lead down several miles to a fiery cavern, where the air ripples with heat distortion and cascades of lava pour down from volcanic fissures in the ceiling miles overhead. The ambitious archdevil Fierna presides, with her grim father Belial as the true power behind the throne.
Stygia lies as deep as Phlegethos, but is many hundreds of miles away from its fiery neighbor—it underlies Dis, and dismal stairs of ice and iron link the two. The fifth Hell is cold and dark. Within Stygia’s cavern lies a vast frozen sea dotted with towering icebergs. Faint auroras of green-blue frostfire dance far above the sea, casting long shadows. Imprisoned within one of these mighty bergs is the archdevil Levistus, trapped forever by Asmodeus for some great betrayal.
Asmodeus’s daughter, the fiendishly beautiful Glasya, rules Malbolge, the sixth Hell. Long, icy canals lead hundreds of miles from frozen Stygia to this great cavern, illuminated by sinister yellow-green lamps suspended from the ceiling like tiny suns. Long ago Malbolge was a vast garden, the delight of the deity who ruled this sphere before Asmodeus, but now its superficial beauty cannot hide a feculent underbelly: autumnal trees with grasping roots, beautiful white towers with corpses impaled on their battlements, shimmering ponds with poisoned waters, and the like.
Maladomini, the seventh Hell, is a tremendous maze of winding tunnels, each miles across. These passages reach several of the lower Hells, including Malbolge, Cania, and Nessus. Within these vast tunnels lie crumbling cities, sludge-filled rivers, and vast tracts of land mined to absolute depletion. Black ichor erupts from the earth, and swarms of flies harry all. Here rules the archdevil Baalzebul, a sluglike monstrosity bereft of compassion.
The icy layer of Stygia seems like a paradise compared to Cania, the eighth Hell. This vast gulf deep within the world is another cold domain, where mile-high glaciers grind across a forbidding landscape so cold that few creatures can bear it. The wickedly handsome archdevil Mephistopheles rules Cania from a palace of ice lit with crackling hellfire.
The darkest of Cania’s rifts plunge hundreds of miles further down to Nessus, the ninth and deepest of the Hells. This is home to the god-tyrant Asmodeus, father of all devils. Nessus is a vast, vertical maze of chasms so large and so deep they are rooted in the seething fires at the core of the cursed sphere. Great infernal cities and fiendish armies lie hidden within these fiery depths.
Succubus
Succubi tempt mortals into performing evil deeds, using their shapechanging abilities to appear as attractive men and women. Although seduction and betrayal are their forte, succubi are also practiced spies and assassins. Succubi serve more powerful devils as scouts, advisors, and even concubines. Because of their guile and shapechanging ability, they are frequently chosen to serve as infernal emissaries to important mortals.

(m) Charming Kiss (standard; at-will) * Charm
+14 vs. AC; on a hit, the succubus makes a secondary attack against the same target.
Secondary Attack: +12 vs. Will; the target cannot attack the succubus, and if the target is adjacent to the succubus when the succubus is targeted by a melee or a ranged attack, the target interposes itself and becomes the target of the attack instead. The effects last until the succubus or one of its allies attacks the target or until the succubus dies.
If the target is still under the effect of this power at the end of the encounter, the succubus can sustain the effect indefinitely by kissing the target once per day. The succubus can affect only one target at a time with its charming kiss.

Succubus Tactics
When exposed for what it is, a succubus can be a deadly foe. It can manipulate the emotions of mortal adversaries, turning them against each other or making them slavishly loyal to it with a mere kiss.
A succubus that is confronted uses dominate on a worthy adversary. It then uses charming kiss on a dominated foe, keeping him or her nearby while it attacks other enemies with its corrupting touch.

War Devil
Champions of the Nine Hells, war devils obey only pit fiends and archdevils. They also lead lesser devils in forays against those who stand in the way of their masters’ plans.

War Devil Tactics
Despite their brutish appearance, war devils are outstanding tacticians and clever leaders. They use besieged foe and fiendish tactics to direct their subordinates against dangerous foes, but they eagerly leap into the fray when the time is right, using devilish transposition to exchange places with a lesser devil (often one with the mobility to penetrate the enemies’ ranks).
War Devil Lore
A character knows the following information with a successful Religion check.
DC 25: War devils (also known as malebranches) are among the most powerful devils that are routinely summoned by mortals.
