Fireball

Fireball /6 ⍟

A fire based, projectile, area of effect spell that deals fire damage to enemies with a high chance to ignite, causing fire damage over time.

Name	Show Full Descriptions
Burning Damage Support	Greatly increases the damage over time dealt by ignites inflicted from Fireball.
Combustion Support	Gives Fireball more fire damage, additional chance to ignite enemies and reduces the fire resistance of ignited enemies. This makes it a great all-round support for any fire based skill.
Deadly Ailments Support	Reduces the hit damage of Fireball in exchange for more ailment damage. This makes it particularly strong for Fireball characters that want to focus on scaling the damage over time of ignites.
Ignite Proliferation Support	Increases the chance to inflict ignites on enemies with Fireball, whilst also enabling ignites to spread to nearby enemies.
Lesser Multiple Projectiles Support	Increases the amount of projectiles Fireball casts, allowing it to hit more targets at once. At later levels, obtain the Greater Multiple Projectiles Support gem to hit enemies in a larger area.
Swift Affliction Support	Decreases the total duration of ignites on enemies but increases the damage that ignites deal, allowing your ignites to burn faster and stronger.

Level Effect /40

Implicit
25% chance to Ignite enemies (Ignite deals Fire Damage over time, based on the base Fire Damage of the Skill, for 4 seconds)

Fireball

Fireball is a spell that fires a projectile, dealing fire damage with an increased chance to Ignite.

Skill functions and interactions

Area of Effect: The radius of the explosion caused by collision (with either an enemy or a terrain obstruction) is affected by all AoE increases, with a base radius of 9. Full spell damage is done to any enemy in range of the explosion.
Pierce, Chain, Fork: Enemies hit by a projectile that pierces, chains, or forks will take full damage from the hit, but the projectile will not explode until it hits an enemy and does not pierce, chain, or fork, or hits a wall.
Shotgunning: Each enemy can only be hit directly by one projectile per cast. However, if an enemy is in range of the explosion effect of more than one projectile from the same cast, and those projectiles each exploded on different enemies or a wall, it will take full damage from each explosion.
Can be used in left mouse button slot to cast and move.
