Item	Description

Version history

Version	Changes
0.3.0	Fireball: No longer creates secondary Firebolt projectiles by default. Instead, it can Consume a Fire Infusion to do so. Now has a minimum Gem level of 3 (previously 9). Primary projectile and explosion now deal 15-22 damage at Gem level 3 (previously 9-14), scaling up to 242-362 damage at Gem level 20 (previously 135-202). Secondary projectiles now deal 22-33 damage at Gem level 3 (previously 10-15), scaling up to 404-606 damage at Gem level 20 (previously 145-218). Secondary projectiles can now hit the same target as the primary projectile.
0.2.1	Added "Barrageable" gem tag.[Undocumented]
0.2.0	Many Skills have had their base damage and/or damage growth per level rebalanced. Most of these changes are not specifically mentioned below as the changes are too widespread. Fireball no longer bypasses the Raging Spirit limit. The secondary Fireball projectiles are no longer affected by additional projectiles, this was mostly to prevent performance issues when used with Wildshards Support.
0.1.0	Introduced to the game.
