Become Fire
Ignite yourself, immediately gaining 2 stacks of Burning for 30 seconds. For 30 seconds, your Magic Attack Power increases by 12% per Burning stack granted by this skill.
This bonus ends when you no longer have Burning.
Effects & keywords
Burning (on user): 3 magic damage per stack, every 1 second (flat, does not scale with attack power; stacks up to 50). Example: 10 stacks = 30 magic damage/second before resistance. Duration is set by the applying skill. It never misses, is never guarded or critical and goes past Barrier, but the target's Magic Resistance still cuts it (x 100 / (100 + resistance)). On a Wet or Heavily Wet target each tick is x0.8.- Magic Attack Power Up: +12% per stack
How the math works
Caster gets 2 Burning for 30s, and 2 Become Fire stacks for 30s. Each Become Fire stack gives 12% Magic Attack Power.
When it runs: On cast, on the caster.
What it applies to: The Magic Attack bonus is on the Become Fire effect, not on Burning. Become Fire stacks cap at the effect table's MaxStack (99); Burning caps at 50.
Things the tooltip does not tell you
- Fireproof doubles the self Burning from this skill but not the Become Fire stacks.
- The per-stack bonus comes from AffecterTable AdjustStatsPerStackData MagicAttackPowerPerModifier with placeholder 3, which binds to this skill FloatValues index 3.
- Become Fire stacks equal the skill's own stack value (FloatValues[1]), not the caster's total Burning at cast time.
- When a Burning removal on the caster leaves 0 Burning stacks, the Become Fire effect on that caster is removed too.

Range and area
This skill is cast on the caster itself. It has no target tile and no area, so there is nothing to aim: it always affects the unit that uses it.
