Firestorm

Template:Gem Infobox 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.

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.

1.0.0	Reduced mana cost.
0.11.2	The damage done by the Firestorm spell when used by all versions of Ambrosia and Merciless Fire Fury has been increased. Merciless Gravicius's Firestorm has been very slightly increased in damage.
0.11.1	Spells with Damage Effectiveness no longer have their own damage affected by Damage Effectiveness. Damage values on these skills have been updated to reflect this.

0.9.11i	Fixed the randomness when it was used with Traps.
0.9.11f	Increased the damage and made its cluster tighter.

0.9.6	Changed Firestorm to be affected less by additional damage from support gems. Fixed a bug where Firestorm could hit monsters through walls.

0.9.3	Firestorm has been added to the game.
