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. Although only a single projectile can hit an enemy, each projectile's explosion can overlap and hit the same enemy.
• Shotgunning: Because Vaal Fireball fires projectiles asynchronously, each fireball can hit the same target.
• Projectile behaviours: 16 projectiles are fired per full clockwise spiral. Adding additional projectiles will increase the number of partial or whole spirals. Vaal Fireball cannot be supported by Volley SupportVolley SupportSupport, Projectile

  • 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
3.23.0	Now has a base Radius of 0.9 metres at gem level 1 (unchanged), scaling up to 1.4 metres at gem level 20 (previously 1 metre). No longer has Projectiles gain radius as they travel farther, up to a maximum of +0-0.9 metres to radius. Quality now provides +0-0.2 metres to radius, instead of 0-20% increased Projectile Speed.
3.16.0	No longer has (50-88)% more Damage with Ignite. It now has 25% chance to Ignite at all gem levels (previously 20-39%).
3.14.0	Now has a Soul Gain Prevention duration of 4 seconds (previously 5). Vaal Skill Gems can now only be obtained from a set of specific methods such as Corrupting Gems, Vaal Side Areas, Divination Cards (that specifically grant Vaal Skill Gems) and the Lapidary Lens in the Temple of Atzoatl.
3.11.0	Now has an added Damage effectiveness of 240% (from 180%). No longer gains additional explosion radius as the gem levels up. 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). Now has an added damage effectiveness of 160% (up from 125%). Now requires 30 souls per use (down from 32). Now prevents you from gaining Vaal souls for 5 seconds after use.
2.0.0	Now has 50% increased Area of Effect at all Levels. Damage adjusted to compensate for damage adjustments 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.
