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.

• 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.

• Positioning: Phasing allows characters to move through monsters. Standing in the exact center of a very large monster while casting vaal fireball will cause most or all fireballs to hit 1 single target. Small rooms will also cause most or all hits against walls to overlap area of effect damage onto 1 target.

Now gains additional explosion radius based on the distance the projectile has travelled as the gem levels up, up to +9 at gem level 20. Now gains 1% increased Projectile Speed per 1% gem quality (previously 0.5% chance to ignite per 1% gem quality).
3.6.0	Adjusted to match the damage and added damage effectiveness of Fireball.
3.3.0	Now deals 7-10 fire damage at gem level 1 (down from 8-11), up to 890-1335 fire damage at gem level 20 (up from 560-841). Now has 20% chance to ignite enemies at gem level 1, up to 39% at gem level 20. Now gains up to +4 to the explosion's radius at gem level 20. Now deals 50% more damage with Ignite at gem level 1, up to 88% more at gem level 20. Now gains 1% chance to ignite enemies per 2% gem quality (down from 2% chance to ignite per 1% gem quality).

2.0.0	Now has 50% increased Area of Effect at all Levels. Damage adjusted to compensate for damage adjustements to Fireball.
1.1.1	If you use a skill that causes a projectile spiral (like Vaal Fireball) from inside an enemy, then only the first projectile can collide with the enemy now.
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.
