S-TIER | BUILD WARLOCK RAMPAGE (@AceofSpades) | SEASON 13

LEVELING WARLOCK

Build Overview

This Warlock leveling build, dubbed "Blue Cannon" by its creator AceofSpades from Goblin Inc, has become the go-to setup for starting the new class on Diablo 4 Season 13. The mechanic at the heart of the build relies on the Rampage skill, transformed by the Abyssal Titan passive into a demon the player can drop from the sky like a meteor. Once paired with the Eviscerate bleed, which deals dozens of times the skill's base damage, the result literally surpasses anything other classes can produce at the same level.

The creator got hands-on access to the class during a Blizzard test session and confirms that this interaction is so strong it has already been nerfed — without the halving really impacting its power. The build is designed as the direct on-ramp to the true Warlock endgame content based around the Abyss, with a smooth power curve across three successive variants: Lvl 1-19, Lvl 20-40 and Lvl 40+. At every tier, the rotation expands to leverage the new tools of the class (Metamorphosis, Sigil, Demoneflesh) without ever losing clarity.

Beyond the numbers, the identity of this build is its simplicity: no rare aspect required, no prior endgame farming, just a direct chain between the class's signature skills and the Eviscerate bleed mechanic. Ideal to discover the Warlock without frustration and smoothly transition to endgame builds once the campaign is done.

Strengths and Weaknesses

Recommended Gear

Being a leveling build, the gear is intentionally minimal. The interactive grid above lists the pieces recommended by AceofSpades for each of the three variants (Lvl 1-19, Lvl 20-40, Lvl 40+). The legendary aspects are deliberately generic so they don't depend on late-game loot.

On chest and pants, the creator alternates between of Omnipower and Aspect of Disobedience depending on the slot, two highly accessible defensive picks that comfortably hold the campaign difficulty thresholds. The amulet always carries Aspect of Slaughter for the movement speed bonus, which noticeably accelerates the leveling pace. On the rings, starting at Lvl 20-40, Aspect of Inevitable Fate is an excellent synergy with the bleed since enemies explode on death, and at Lvl 40+ Brawler's Aspect boosts damage right after using the ultimate — exactly the moment when the rotation peaks.

For the weapon, AceofSpades explicitly recommends simply running "whatever has the highest damage" and not engraving any aspect on it as the piece will be replaced frequently during the campaign.

Build Variants

The build splits into three successive variants that follow the natural unlocks of the Warlock class. Understanding this progression avoids early-level frustration and lets you exploit each tool the moment it becomes available.

Variant Lvl 1-19 — Before level 20, Rampage exists but cannot yet be modified, which makes the skill rather underwhelming as is. The basic skill of the moment is therefore Hellion Sting, which can also trigger Eviscerate (45% chance, 660% bleed damage). As support, Dread Claws covers waves of monsters and Nether Step handles mobility. The ultimate stays secondary during this phase.

Variant Lvl 20-40 — The build reaches its full scale as soon as the modifiers of Rampage become accessible. The skill becomes the main burst for elites and Bosses, while Hellion Sting is replaced by Command Fallen, which summons three small demons that generate resources on contact. Sigil of Subversion joins the bar to stack Shadow Form charges — these charges are the actual fuel for the bursts via the Mastermind Shard.

Variant Lvl 40+ — The sigil makes way for Metamorphosis. The Terror Demon Metamorphosis passive adds every rank invested in Metamorphosis to all Abyss skills, including Rampage. With fifteen ranks, the cumulative effect across the rotation is massive. The transformation granted by the ultimate also produces four Shadow Form charges per second, which makes the Mastermind Shard devastating during prolonged Boss phases.

Gameplay Tips

Dominance management is the key to the build. This secondary resource (the purple bar next to mana) cannot be amplified by aspects and regenerates slowly, which makes every cast of Rampage a decision: in early leveling, save the burst for elites and quest phases rather than for small monster packs. Once in the Lvl 40+ variant, the transformation ultimate is enough to push the class into a mode where dominance regenerates naturally.

The other central point is the stacking of Shadow Form charges. The logic is simple: Sigil of Subversion drops trails that generate them as the player walks through, while the final transformation replaces this device with a passive flow of four charges per second. The Mastermind Shard, which consumes two charges per cast to boost damage by 30%, is the actual amplification mechanic — the Blasphemous Fragment is preferred until the main skill gets the "recast" mod from the modifiers of Rampage at level 20.

For the rotation, the ideal tempo in zones is: drop Command Fallen at the start of a pack (it's a 20-second buff, you forget about it), clear the melee with Dread Claws, reposition with Nether Step, and unleash Rampage on the elite or the most dangerous pack. The skill triggers Eviscerate on every hit thanks to the associated passive, and the chain of bleeds multiplied by the ranks of Metamorphosis finishes the work on its own while you move to the next pack.
