Fireball

Mage skill · Fire line · tier 1

Beta 0.7.2

The first spell every mage learns, and the last one they give up.

It is only used in combat once it is placed on the hero's active bar, and its 6 s cooldown is before cooldown reduction.

Values by rank

Fireball scales with Fire Damage. Its value at each rank is 10 + 2.9 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	12.9	15.8	18.7	21.6	24.5	27.4	30.3	33.2	36.1	39

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.
