''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==
'''Firestorm''' is a [[spell]] that rains numerous fiery bolts in an area, each bolt dealing [[area of effect]] [[fire damage]].
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.
[[Skill Duration|Duration]]: Increasing duration with either supports or passives will increase the total number of fireballs that fall before the spell ends.
==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. However, increasing the size of the spell area means that each monster within the spell area is within fewer individual fireball bursts<ref>While each fireball takes up the same proportion of the total area as the radius of both increases proportionally, the monster's radius does not change, so it takes up less of the spell area. Thus, the probability for a given fireball to hit the monster goes down as AOE goes up.</ref>; thus, less spell damage is dealt to any single enemy as area increases. For this reason increasing the AoE of Firestorm paradoxically decreases the average damage dealt to a single target.
Low Damage Effectiveness: This stat causes the base spell damage, as well as added damage from supports such as [[Added Lightning Damage|Added Lightning]]/[[Added Cold Damage|Cold]]/[[Added Chaos Damage|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.
'''[[Skill Duration|Duration]]''': Increasing duration with either supports or passives will increase the total number of fireballs that fall before the spell ends.
==Gem Leveling==
'''[[Damage Effectiveness]]''': Damage from secondary sources like 'added damage' supports or heralds applies at only 80% of their listed value.

'''Damage per Second''': Due to the complexity of estimating actual DPS of the skill including all possible factors, ingame tooltip shows only average damage per hit of one fireball, with actual DPS of the skill being considerably higher. The closest currently available estimate can be obtained by using the [https://docs.google.com/spreadsheets/d/1__amWXx4uPtt-ywgULZ7Rx86_A0lqhaLkqK4KHsU-TU/edit#gid=361993092 damage calculator].

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. However, increasing the size of the spell area means that each monster within the spell area is within fewer individual fireball bursts[1]; thus, less spell damage is dealt to any single enemy as area increases. For this reason increasing the AoE of Firestorm paradoxically decreases the average damage dealt to a single target.

Damage per Second: Due to the complexity of estimating actual DPS of the skill including all possible factors, ingame tooltip shows only average damage per hit of one fireball, with actual DPS of the skill being considerably higher.

Quest reward
This item is given as a quest reward for the following quests:
Note that helmet enchantments are no longer obtainable since version 3.23.0 and can only be obtained in permanent leagues as already enchanted items from before this patch.
Quality on Anomalous Firestorm no longer grants “(0.00)-(-0.06) seconds to Base Duration”, or “First Impact deals 0-60% more Damage with Hits and Ailments”. Instead, it now grants 0-10% chance to Ignite Enemies.
Because of base Ignite damage changes, Ignite with the skill is now 150% higher. If using the Anomalous quality, the Ignite is now 110% higher.
Firestorm now calls down a large meteor that impacts the targeted location, followed by a series of smaller impacts at set intervals over the storm's duration. The base power of the spell has been significantly raised, so you are now limited to three Firestorms at any given time (any new storms created will replace the oldest).
Now requires level 28 at gem level 1 (from 12). Please be aware that existing low level characters with Firestorm socketed may have that gear slot disabled until the Firestorm gem is removed.
Now has a mana cost of 13 at gem level 1, up to 25 at gem level 20.
Now has an added damage effectiveness of 50%.
Now deals 22 to 33 fire damage at gem level 1, up to 207 to 311 fire damage at gem level 20.
Now has a base duration of 1.4 seconds with one impact every 0.2 seconds.
The first impact now has 100% more area of effect and deals 150% more damage.
Now has alternative quality:
Anomalous: First Impact deals 3% more damage and Base duration is -0.003 seconds (per 1% quality)
Firestorm: Had a very slight damage buff. Area of effect of explosions increased by 11% (9 to 10). It now grants 1% area damage per 1% quality instead of reduced delay between fireballs. The Duration of Firestorm has been increased from 1.3 seconds to 2 seconds at all levels. Base Cast Speed has been increased from a cast time of 1 second to 900ms. Critical Strike Chance has been increased from 5% to 6%.
Firestorm: The radius of the area that fireballs land in has been increased by 39%. The delay between strikes has been reduced from 0.15 seconds to 0.10 seconds. Damage has been increased by 35%. The quality bonus has been reduced by 33.33% to match the reduced projectile delay.
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.
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.
Added new skill prototype - Firestorm: Flaming bolts rain down over the targeted area. They explode when landing, dealing damage to nearby enemies.
References
↑While each fireball takes up the same proportion of the total area as the radius of both increases proportionally, the monster's radius does not change, so it takes up less of the spell area. Thus, the probability for a given fireball to hit the monster goes down as AOE goes up.
