Watch for Lava Waves - His Most Lethal Ability

One of Azmodan's signature mechanics is the massive lava waves he casts both in front of and behind his massive frame. These waves expand in size as the fight progresses and Diablo 4 Items can easily one-shot players in higher Torment tiers.

If you're melee:

Move completely to the side and stay tight against his flank.
If you're ranged:
Maintain distance and pre-move before the animation completes.

80% Phase - Slow Lava Breath

At around 80% HP, Azmodan begins using a slow, sweeping lava breath attack. It has a longer wind-up and is easier to dodge than his other abilities, but getting clipped will melt your health bar instantly.

Strategy:

Strafe diagonally to avoid the cone.
Use mobility skills after you see the cast begin, not before.

60% Phase - Balrog Add Wave

At 60% health, Azmodan summons a pack of Balrog-type demons. These demons hit hard but have low health relative to other Elite waves.

Kill priority:

1. Balrogs
2. Avoid spikes
3. Re-engage the boss

Clearing quickly prevents the arena from D4 materials for sale becoming a chaotic hazard zone.
