Lava Lich Eruption Pyromancer
PyromancerPyromancer build that leans on the Lava Lich armor set to double Eruption damage and cut 30% off its cooldown. Ash Blast applies the Death Sentence debuff, Overheat consumes Burn and Ash for a 150% damage spike, and Eruption finishes with up to three stacked charges scaling through the Trigger Sequence bonus.
Damage
Three-charge Eruption burst reaches into the millions of Anomaly damage at Apocalypse Tier 40
Survivability
24% Max Health heal on every marked-enemy kill keeps the build topped off through skill uptime
Boss
Clears Trial of Tarya Gratar and Arbiter with the Ash Blast into Overheat into 3x Eruption rotation
Pyromancer
Medium-range caster class that scales skill damage through Anomaly Power and heals through its Class Trait: skills mark enemies for 15 seconds, and killing a marked target restores 24% Max Health. The Tempest class tree turns skills into explosive damage dealers that stack cooldown reduction and Anomaly Power bonuses.
Legendary automatic shotgun used as a mod-proc platform. A single shot fires Shadow Comet and Firestorm AoE pulses at the feet of a pack, softening them up before the skill rotation starts.

Mods & Attachments
- ▸Mod: Arms and Anomaly— Built-in mod. ~650K Anomaly Power buff at Apocalypse Tier 40
- ▸Mod: Anomaly Echo— +400K Anomaly Power buff for several seconds after casting a skill
- ▸Apocalypse: Death Sentence— Ash Blast applies a 30% Anomaly Damage debuff that shares with every party member's Anomaly skills
Alternatives
- Helmet of the Lava LichWiki
How to Obtain
Wearing any three of Helmet, Upper Robe, Lower Robe, Charms, or Boots of the Lava Lich activates the keystone bonus: +100% Eruption damage and -30% Eruption cooldown. Ronin's Amigasa does NOT count toward this, so the 3 pieces must come from the Lava Lich set itself (chest, pants, and gloves in this build).
Combat Strategy
- ▸Empty pistol magazines before entering an expedition. Moaning Winds and Radiation Splash mods proc the moment the pistol is swapped in.
- ▸Equip Upper Robe, Lower Robe, and Charms of the Lava Lich to activate the 3-piece bonus: +100% Eruption damage and -30% Eruption cooldown.
- ▸Roll Status Power on at least four gear pieces so Ash lasts long enough for Overheat to consume it at Apocalypse Tier 40.
- ▸Fire one Funeral Pyre shot to drop Shadow Comet and Firestorm pulses across the pack.
- ▸Cast Ash Blast, then wait two seconds for the Ash field to fully propagate across every enemy.
- ▸Cast Overheat to consume Burn and Ash together for a 150% damage multiplier via Master Consumer.
- ▸Open with Ash Blast to apply Death Sentence, a 30% Anomaly Damage debuff that shares with every party member's skills.
- ▸Weapon-crit twice with the secondary AR or SMG to stack Fortress for +25% damage and Mages Rage for up to +60% Anomaly Power.
- ▸Cast Overheat to build the first Trigger Sequence stack.
- ▸Fire three Eruption charges back-to-back. The second gains +35% damage, the third stacks to +70% via Trigger Sequence.
- ▸Proc Firestorm with Funeral Pyre and Mages Rage plus Fortress with the secondary before the damage window opens.
- ▸Cast Overheat first to bank a Trigger Sequence stack before Ash Blast applies Death Sentence.
- ▸Cast Ash Blast, then fire three Eruption charges in sequence. The third charge requires the Pompeii mod rolled on gear.
- ▸Eruption cannot target enemies until they have fully spawned on the map. Hold the cast through the spawn animation to avoid a wasted skill.
- ▸The Overheat-after-Ash-Blast map clear fails if cast too early. Wait the full two seconds after Ash Blast for the field to settle.
- ▸Swap Overheat for Thermal Bomb with the Branded mod during boss-only gear swaps when single-target burst matters more than map-wide clear.
