Lune Burn & Stain Build Guide
Updated September 2026 · base-game stats
Hell is Lune's pay-off skill: very high Fire damage to all enemies, 5 Burn per hit, and it consumes Stains for a huge damage bonus. This guide covers the unlock path, how Burn and Stains stack, and a calculator-ready loadout.
How to unlock the core skills
Hell sits deep in Lune's skill tree behind Fire Rage (which itself needs Wildfire). Lightning Dance needs Electrify, and Elemental Trick — the Stain generator — needs Mayhem.
Hell →What the core skills do
- Hell — very high Fire damage to all enemies, 2 hits, applies 5 Burn per hit; deals self-damage if failed (9 AP).
- Fire Rage — increasingly high Fire damage every turn until Lune takes damage; Stuns self if interrupted (5 AP).
- Elemental Trick — 4 hits across Ice/Fire/Lightning/Earth; Critical Hits generate the corresponding Stain.
Why the damage stacks so high
Burn in Expedition 33 stacks per application. Double Burn adds a second Burn stack every time you apply one, and Burn Affinity multiplies all damage against Burning targets by ×1.25. Hell then dumps 5 Burn per hit × 2 hits on every enemy while cashing Stains for its greatly-increased damage — each of these sits in a different damage category, so they combine multiplicatively (base × skill × bonuses × crit).
Sample endgame loadout
Kralim — Lune's Lightning weapon: initial-defeat drop from an enemy group on The Continent, also dropped by the Chromatic Orphelin in Yellow Harvest.
Kralim →- · Burn Affinity — +25% damage on Burning targets: multiplies everything Hell does.
- · Double Burn — every Burn application applies a second stack, doubling Burn ramp.
- · Glass Cannon — +25% damage, at the cost of taking 25% more damage.
The loop: open with Immolation or Fire Rage to stack Burn (Double Burn doubles it), generate Stains with Elemental Trick crits, then cash everything into Hell — burning target enabled — for a full-screen nuke.
