Firestorm

Perhaps the most feared area effect skill in the Witch's arsenal, the mighty Firestorm skill is legendary for its power and cruelty. The incantation tears a rift in the heavens that showers a wide swath of ground in a rain of searing flames. These bolts pound down without mercy, burning everything they touch, then exploding violently to cause even more harm.

Flaming bolts rain down over the targeted area. They explode when landing, dealing damage to nearby enemies.

Skill Functions and Interactions

Area of Effect: Increased AoE will increase both the area in which the fireballs randomly fall and also the radius of the individual fireball damage. Full spell damage is done at any point within the AoE of a fireball.

Duration: Increasing duration with either supports or passives will increase the total number of fireballs that fall before the spell ends.

Low Damage Effectiveness: This stat causes the base spell damage, as well as added damage from supports such as Added Lightning/Cold/Chaos Damage, to be only 20% of their listed effectiveness. This limits the effectiveness of adding base damage to spells that create many small hits instead of one large effect.
