What is the Warlock in D2R?

The 8th playable class — the first new class added to Diablo II in 25 years. Released with the Reign of the Warlock expansion. Warlocks are dark scholars who bind demons with hellish magic. They wield Grimoires — spellbook off-hands no other class can use — and can Bind Demon to turn Super Unique monsters into permanent pets.

Is the Warlock still S-tier after the 3.2 PTR changes?

Mostly. The PTR tested heavy Echoing Strike nerfs (synergy bonus reduced, additive instead of multiplicative). Summoner Warlock and Mirrored Blades Warlock look like safer top picks if those changes ship. Echoing Strike remains viable but no longer dominates on the PTR.

Warlock's signature passive that lets you wield a two-handed weapon and a Grimoire off-hand at the same time. Patch 3.2 PTR tested restricting this to Grimoires only, with no shield off-hand.

Warlock — D2R Class Guide

By the DiabloBytes team · Updated May 22, 2026 · Season 14 / Patch 3.2 (Live)

The Warlock is the first new Diablo II class in 25 years. Dark scholars who bind demons to their will, wielding forbidden hellish magic through Grimoires — spellbook off-hands no other class can use. Hybrid caster/summoner/melee. Three viable paradigms via one class. Still strong on the Patch 3.2 PTR even after the tested Echoing Strike nerfs.

◆
Levitate
Two-handed weapon + Grimoire off-hand simultaneously. Patch 3.2 PTR tested Grimoire only, no shields.

◆
Blade Warp
Level 18 skill — effectively free Teleport without Enigma.
◆
Grimoires
Warlock-exclusive off-hand item class — spellbooks with runeword slots + unique affixes.

Leveling Path

Start with Miasma Bolt. Levels 6-12 add Sigil Lethargy + Miasma Chains for AoE. At 12 take Echoing Strike or continue Chaos. 1 point in Levitate ASAP regardless. At 18 grab Blade Warp for mobility + Blood Boil if Demon. Respec at Act 5 Normal into final build. 24+ unlock synergies (Mirrored Blades / Apocalypse / Abyss all at 30). Use Spirit sword + Rhyme grimoire until Void/Ritual. Insight polearm merc handles mana.
