Combustion

Mage skill · Fire line · tier 2

Beta 0.7.2

The fire doesn't go out: it finds whatever is left to burn.

It is only used in combat once it is placed on the hero's active bar, and its 8 s cooldown is before cooldown reduction.

Values by rank

Combustion scales with Burn. Its value at each rank is 23.5 + 6.7 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	30.2	36.9	43.6	50.3	57	63.7	70.4	77.1	83.8	90.5

The value is the game's internal number for this skill.

in combat = round(value × skill power × max(0.35, hero damage ÷ 600))
hero damage = Attack + all elemental damage
skill power = 1 + 1% per point in the other Fire skills + 2% per rank of each skill that boosts it

The damage factor has a minimum of 0.35 and no maximum. A hero with 600 damage and no line mastery or synergies gets the listed value; how it becomes damage or healing per hit depends on the skill's type and timing.

Combustion has no synergies: no skill boosts it and it boosts no other skill.
