Spark is a projectile lightning spell skill that launches a spray of lightning sparks in front of the character that move in an erratic fashion. These projectiles can bounce off terrain and last until it expires or hits an enemy. If you have a Cold Infusion, it is consumed to release additional icy sparks in a circle that deal cold and lightning damage.

Skill functions and interactions

The speed of the projectiles created by Spark can be increased or decreased by projectile speed.

Item	Description

Version history

Version	Changes
0.3.0	The base damage scaling of all player spell and secondary damage skills has been tweaked to scale better in the late game. Generally speaking, spells that do not have damage number changes called out below will have near-identical base damage at low levels, roughly 5% more damage at gem level 20, and roughly 20% more damage at gem level 30. Spark: Can now be Cold-infused to fire a large number of icy sparks in a circle, dealing both cold and lightning damage.
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. Spark now fires 4-9 Projectiles at gem levels 1-20 (previously 6-14), and no longer has 0-19% increased Projectile Speed. Quality now provides 0-30% increased Projectile Speed (previously Fires +0-4 Projectiles).
0.1.0	Introduced to the game.
