Vaal Fireball

For the non-Vaal counterpart, see Fireball.

Vaal Fireball is a vaal spell that launches fireballs in all directions around the character. The fireballs will launch rapidly one at a time rotating clockwise around the player, continuing until all 32 fireballs have been launched.

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. Full spell damage is done to any enemy in range of the explosion. The threshold jewel Rolling FlamesRolling Flames

• Piercing: A fireball that pierces an enemy and hits another enemy will only cause the AoE damage effect on the last enemy struck. Any enemies hit by a projectile which successfully pierces or chains will take full spell damage but the projectile won't explode.

• Fork: Fork creates new projectiles on impact, and fireball explodes on impact, regardless of whether it is a first-generation projectile or a forked, second-generation projectile. Thus, the initial fireball projectile causes an explosion on impact, this impact spawns forked projectiles; the forked projectiles will also explode when making impact with a valid target.

Version history

Version	Changes
2.0.0	Now has 50% increased Area of Effect at all Levels. Damage adjusted to compensate for damage adjustements to Fireball.
1.1.0d	Vaal Skill soul counts were initially balanced for Merciless difficulty, where there are more monsters. We want them to be easier to use in Normal and Cruel difficulty. We have halved the number of souls required for each skill. In Cruel difficulty, skills require 50% more souls to uses. In Merciless difficulty, they require 100% more (which is the same as before the patch).
1.1.0	Introduced to the game.
