Warlock Class Guide — Reign of the Warlock
By the DiabloBytes team · Updated March 2026
Class Overview
The Warlock is the eighth playable class in Diablo II: Resurrected, introduced with the Reign of the Warlock expansion (Patch 3.0). It is a hybrid caster-summoner-melee class that wields daggers and Grimoires, commands demons, and deals fire and magic damage through curses, sigils, and direct-damage spells. The class starts with Miasma Bolt as its default skill and a dagger equipped.
What sets the Warlock apart from every other class is the Levitate passive ability. Levitate allows the Warlock to wield two-handed weapons alongside an off-hand item (Shield or Grimoire). This creates weapon and runeword combinations that no other class can access — for example, equipping a two-handed polearm with Spirit runeword while still carrying a Grimoire in the off-hand.
The Warlock's three skill trees are Demon (summoning and blood magic), Eldritch (melee combat, hex debuffs, and movement), and Chaos (fire damage, sigil curses, and miasma spells). Each tree supports distinct endgame builds, and the class has enough cross-tree synergy to enable several hybrid configurations.
Starting Attributes
Levitate — Signature Passive
Levitate is a level 1 passive in the Eldritch tree that is available from character creation. Its defining mechanic is allowing the Warlock to equip a two-handed weapon in the main hand while simultaneously using an off-hand item (Grimoire or Shield). This is unique among all D2R classes — no other character can wield a two-handed weapon and a shield at the same time.
This opens up powerful gear combinations: you can use two-handed runewords like Insight, Infinity, or Breath of the Dying while still carrying a Spirit Monarch or a Grimoire with +skills staff mods in the off-hand. Investing points in Levitate provides additional passive bonuses to weapon handling. Every Warlock build should put at least one point into Levitate.

Warlock Build Tier List & Overviews
Skill Tree 1 — Demon
The Demon tree focuses on summoning demonic minions and empowering them through blood magic. It contains three summon skills (Goatman, Tainted, Defiler), two passives (Demonic Mastery, Blood Oath), and several active skills that interact with your summons. The tree peaks with Bind Demon at level 30, which allows you to capture Super Unique monsters as permanent allies — retaining their native auras and affixes like Conviction or Fanaticism. Consume lets you sacrifice minions for personal buffs to damage, life, and movement speed.
Summons a Goatman demon that fights in melee. Gains Stun, Berserk, Frenzy, and Cleave sub-skills as the base skill levels. Max summon count scales with Demonic Mastery (1 at base, 2 at level 10, 3 at level 20). HP scales per level and with Blood Oath synergy. Crushing Blow via Death Mark synergy.
Passive aura that increases summon velocity, attack rating, damage, and attack speed for all Warlock demons. Unlocks additional Goatman summon slots at levels 10 and 20. Prerequisite: Summon Goatman.
Marks a target, reducing its defense and resistances. Each point invested grants Crushing Blow synergy to Summon Goatman. Prerequisite: Summon Goatman.
Passive that grants life, damage, and damage resistance bonuses to summoned demons. Also provides synergy HP bonus to all summon skills. Prerequisite: Demonic Mastery.
Summons a Tainted demon. Stronger than the Goatman with higher base damage. HP scales per level and with Blood Oath synergy. Prerequisite: Summon Goatman.
Deals fire damage in an area. Damage values scale across multiple tiers as skill level increases. Prerequisite: Death Mark.
Summons a Defiler demon — the most powerful standard summon. Higher base damage and defense than Tainted. HP scales per level and with Blood Oath synergy. Prerequisite: Summon Tainted.
Buffs a summoned demon, increasing its size, life, damage, and run speed. Makes a single demon significantly more powerful for a duration. Prerequisite: Blood Boil.
Sacrifices a minion or Super Unique to grant the Warlock bonuses to physical, fire, or magic damage, maximum life, and faster run/walk. Works on your own summons and on captured Super Uniques. Prerequisite: Blood Oath.
Captures a Super Unique monster as a permanent ally, retaining its native affixes (Conviction, Fanaticism, etc.). Gains additional abilities at skill levels 5, 10, 15, and 20. Provides damage reduction when paired with Blood Oath. Prerequisites: Engorge + Summon Defiler.
Skill Tree 2 — Eldritch
The Eldritch tree provides the Warlock's melee combat skills, hex debuffs, defensive abilities, and movement. Levitate (the signature passive) anchors the left column, leading into Cleave, Echoing Strike, Blade Warp, and Mirrored Blades for melee/movement. The right column contains the Hex line (Hex Bane, Hex Purge, Hex Siphon) for ranged magic damage and sustain. Psychic Ward and Eldritch Blast sit in the center, connecting the two columns. Blade Warp at level 18 is the Warlock's teleport — it passes through walls and barriers, providing the class's primary map traversal.
Warlock's signature passive. Allows wielding two-handed weapons alongside an offhand (Shield or Grimoire), creating unique weapon + runeword combinations unavailable to any other class. Also grants passive bonuses to weapon handling.
Ranged magic-damage attack with a long duration debuff component. Damage boosted by Eldritch Blast synergy. One of the Warlock's two starting skills.
Melee attack that hits in an arc. Damage synergizes with Mirrored Blades, Hex Purge, and Eldritch Blast. Gains additional target radius at higher levels. Prerequisite: Levitate.
Melee strike that echoes additional hits. Mirrored Blades synergy adds echo count. Strong area clear skill for the Eldritch tree. Prerequisite: Levitate.
Magic damage attack that scales in number of projectiles with level (up to 3). Synergy with Eldritch Blast for damage and Sigil Death for secondary effects. Prerequisite: Hex Bane.
The Warlock's movement skill. Teleports through walls and barriers while dealing magic damage. Functions as the class's primary mobility tool, similar to Teleport. Prerequisite: Echoing Strike.
Creates a protective ward that absorbs incoming damage. Provides a defensive buffer for the Warlock during combat. Prerequisite: Cleave.
Powerful magic damage skill that serves as the Eldritch tree's primary ranged damage dealer. Provides synergy bonuses to Hex Bane, Hex Purge, and Hex Siphon. Prerequisite: Psychic Ward.
Drains life/mana from targets. Damage scales with Eldritch Blast synergy. The Hex line's sustain skill. Prerequisite: Hex Purge.
Creates mirrored blade projectiles (up to 5 at high level). Provides synergy echo count to Echoing Strike. Strong AoE damage skill. Prerequisites: Blade Warp + Eldritch Blast.
Skill Tree 3 — Chaos
The Chaos tree splits into three columns: fire damage (Ring of Fire → Flame Wave → Apocalypse), sigil curses (Sigil Lethargy → Sigil Rancor → Sigil Death), and miasma/entropy magic (Miasma Bolt → Miasma Chains → Enhanced Entropy → Abyss). Fire builds use the left column to deal massive area fire damage culminating in Apocalypse. Magic-damage builds focus on the right column, using Miasma Chains and Abyss for magic damage that bypasses fire immunities. The Sigil line in the center provides crowd control and damage amplification that benefits both paths.
The Warlock's starting skill (assigned by default). Fires a bolt of magic damage at a single target. The baseline ranged attack for leveling.
Creates a ring of fire around the Warlock dealing fire damage to nearby enemies. Radius increases at level 10. Prerequisite for Flame Wave.
Places a sigil that slows enemy movement and attack speed. Reduces enemy damage output. The Warlock's primary crowd control skill.
Upgraded sigil that amplifies damage taken by affected enemies, building on Lethargy's slow. Prerequisite: Sigil Lethargy.
Chains of magic damage that link between nearby enemies. Bounces to multiple targets for area clear. Prerequisite: Miasma Bolt.
Sends a wave of fire across the ground. Strong AoE fire damage skill. Prerequisite: Ring of Fire.
The most powerful sigil. Deals direct damage and triggers an explosion on enemy death. The capstone of the Sigil line. Prerequisite: Sigil Rancor.
Passive that increases all magic and elemental skill damage. Boosts fire, magic, and physical damage percentages. The Chaos tree's damage multiplier. Prerequisite: Miasma Chains.
Rains fire damage across a large area. The Chaos tree's ultimate fire skill. High damage output over a wide radius. Prerequisites: Flame Wave + Sigil Death.
Creates a zone of magic damage that persists on the ground. The Chaos tree's ultimate magic skill. Prerequisite: Enhanced Entropy.
Key Skills Explained
- Levitate (Eldritch, Lvl 1) The passive that defines the class. Allows two-handed weapons + off-hand simultaneously. Always take at least 1 point.
- Blade Warp (Eldritch, Lvl 18) The Warlock's teleport. Passes through walls and barriers. Essential for map traversal in every build. Available at level 18, removing the need for Enigma for basic mobility.
- Bind Demon (Demon, Lvl 30) Captures a Super Unique as a permanent ally that keeps its native affixes. A Conviction-aura Super Unique becomes your personal Infinity. Gains abilities at skill levels 5, 10, 15, and 20.
- Consume (Demon, Lvl 30) Sacrifice a minion or captured Super Unique for bonuses to physical/fire/magic damage, max life, and FRW. Enables a "sacrifice loop" playstyle: summon demons, consume them for buffs, resummon.
- Echoing Strike (Eldritch, Lvl 12) Melee attack with echo hits. Number of echoes scales with Mirrored Blades synergy. Core skill for the Echoing Strike build archetype.
- Apocalypse (Chaos, Lvl 30) The Chaos tree's ultimate fire skill. Massive AoE fire damage. Requires both Flame Wave and Sigil Death as prerequisites.
- Abyss (Chaos, Lvl 30) Persistent ground zone dealing magic damage. The Chaos tree's magic-damage capstone. Scales with Enhanced Entropy passive. Abyss Warlock is a top-tier endgame build.
- Blood Boil (Demon, Lvl 18) Area fire damage skill in the Demon tree. Core of the Blood Boil build archetype. Damage tiers scale across multiple breakpoints as skill level increases.
Breakpoints
The Warlock shares the same cast, hit recovery, and block animation frames as the Necromancer. The key FCR targets are 75% (10 frames) for comfortable casting and 125% (9 frames) for maximum speed.

Recommended Builds
Five endgame archetypes are established for the Warlock. Fire Warlock and Abyss Warlock are also the recommended leveling paths.
- Fire Warlock Chaos TreeFocuses on Ring of Fire → Flame Wave → Apocalypse. Max Apocalypse and Flame Wave for damage, invest in Sigil Rancor and Sigil Death for the damage amplification and Apocalypse prereqs. Enhanced Entropy passive boosts all damage. Strong leveling build. Weakness: fire immunities in Hell. Pair with Infinity mercenary or hybridize with Abyss.
- Abyss Warlock Chaos TreeBuilt around Abyss (magic damage ground zone) and Enhanced Entropy passive. Uses Miasma Bolt → Miasma Chains → Enhanced Entropy → Abyss. Magic damage bypasses most immunities, making this the safer Hell build. Supplement with Sigil Lethargy/Rancor for crowd control. Good leveling path through the Chaos tree.
- Echoing Strike Warlock Eldritch TreeMelee build using Echoing Strike and Mirrored Blades for echo-based AoE clear. Requires Levitate → Echoing Strike → Blade Warp → Mirrored Blades path, plus Cleave → Psychic Ward → Eldritch Blast for the Mirrored Blades prereqs. Blade Warp provides built-in teleport. High gear dependency (needs strong weapon + FCR for casting speed).
- Blood Boil Warlock Demon TreeUses Death Mark → Blood Boil → Engorge as the core damage loop. Blood Boil deals fire AoE while Death Mark reduces enemy defenses. Engorge can buff summons for a hybrid approach. More defensive than pure Fire Warlock thanks to demon meat shields. Works well with Consume for additional damage buffs.
- Summoner Warlock Demon TreeFull summoner build. Max Summon Goatman, Summon Tainted, Summon Defiler, Demonic Mastery, Blood Oath. Use Death Mark to debuff targets. Endgame capstone is Bind Demon to capture a Super Unique with a powerful aura. Consume lets you sacrifice summons for temporary self-buffs when needed. Safest playstyle but slowest clear speed.
Stat Allocation
The Warlock gains 5 stat points per level. The allocation follows the standard caster pattern, with Vitality receiving the bulk of points.
Grimoire — Exclusive Off-Hand
Grimoires are the Warlock's class-exclusive off-hand item type. They function like shields (providing defense and block chance) but can also spawn with +1 to +3 staff mods to Warlock skills. There are 15 Grimoire bases across Normal, Exceptional, and Elite tiers. Grimoires can be socketed and used as runeword bases — the Vigilance runeword (Dol + Gul) is specifically designed for Grimoire bases.

| Old Book | Normal | 2-5 | 12 | 3% | 3 |
| Tome | Normal | 4-8 | 14 | 5% | 6 |

Gear Recommendations
Warlock gearing follows three phases: budget runewords for Normal/Nightmare, mid-tier RotW-specific gear, and endgame best-in-slot. Levitate's ability to pair 2H weapons with off-hands gives the Warlock more gearing flexibility than any other caster. The Runeword Guide covers crafting details.
Reign of the Warlock Runewords
Patch 3.0 introduced five new runewords that interact with Warlock skills. Authority and Coven are the most accessible (budget-to-mid rune cost). Void is the most expensive due to Zod but provides best-in-slot caster stats for dagger builds.

Mercenary Recommendations
The mercenary choice depends on your build and what it lacks. Summoner builds want auras that buff minions, while caster builds want crowd control or immunity-breaking.
- ▸ Act 2 NM Offensive (Might) Best for Summoner and Echoing Strike builds. Might aura directly buffs your summoned demons' physical damage and your own melee strikes. Equip with Insight for mana sustain or Infinity to break immunities.
- ▸ Act 2 NM Defensive (Holy Freeze) Best all-around choice for caster builds (Fire, Abyss). Holy Freeze slows enemies, providing crowd control while you position Apocalypse, Abyss, or Flame Wave. Equip with Infinity to handle fire-immune monsters.
- ▸ Act 2 NM Combat (Prayer) Solid for Blood Boil builds or any build that trades HP for power. Prayer provides passive life regeneration. Pairs exceptionally well with Insight (Meditation + Prayer = double healing).
- ▸ Act 5 Barbarian Battle Cry reduces enemy defense and damage, providing strong survivability support. The Barbarian's natural tankiness keeps him alive longer than Act 2 mercenaries in dangerous content. Good for hardcore Warlock play.
- ▸ Act 1 Rogue (Fire Arrow) Budget option for early game. Provides ranged damage support. Equip with an Insight bow for mana. Outclassed by Act 2 mercenaries in endgame.
Leveling Tips
The Warlock starts with Miasma Bolt (magic damage) and a dagger. Early leveling is straightforward: use Miasma Bolt as your primary attack and pick up Summon Goatman at level 1 for a meat shield. At level 6, Ring of Fire or Sigil Lethargy add area damage or crowd control.
- Levels 1-5 Use Miasma Bolt. One point in Summon Goatman for a companion. One point in Levitate (always). If going Eldritch, take Hex Bane as well.
- Levels 6-11 Fire path: Ring of Fire for area damage. Chaos path: Sigil Lethargy for crowd control. Eldritch path: Cleave for melee. Demon path: Death Mark + Blood Oath.
- Levels 12-17 Fire/Chaos: Miasma Chains or Sigil Rancor. Eldritch: Echoing Strike for melee clear. Demon: Summon Tainted for a stronger summon.
- Levels 18-23 Blade Warp unlocks (Eldritch tree) providing teleport. Flame Wave (Chaos tree) or Blood Boil (Demon tree) for area damage. Psychic Ward for defense.
- Levels 24-29 Enhanced Entropy passive (Chaos) for damage multiplier. Eldritch Blast, Sigil Death, or Engorge depending on build. Hex Siphon for sustain.
- Levels 30+ Capstone skills unlock: Apocalypse, Abyss, Mirrored Blades, Consume, Bind Demon. Max your primary damage skill, then invest in synergies and passives.
