Spark

Spark is a lightning spell that releases erratic projectiles with a duration. The public record gives level-dependent projectile counts and a separate interaction that consumes Cold Infusion to fire a circular pattern of cold and lightning sparks. The ordinary projectile behaviour and the infusion version should remain distinct when interpreting a demonstration.

Projectile count, duration and mana cost are separate values. More time for a projectile to exist does not by itself establish how many times a particular enemy will be hit, and a source describing the base gem cannot supply a whole build's damage. Room shape, positioning and the rest of the skill setup are therefore relevant questions for a guide to explain. Pierce, Prolonged Duration, Considered Casting and Electrocute are listed support candidates that address different mechanics. Check which effect the chosen setup is trying to change instead of copying every candidate into a single socket list. Spark has been present since the Early Access introduction record and is the starting spell in the Sorceress card. That class page supplies the elemental-caster context, while the duration-support page explains the older Persistence alias that can appear in dated Spark guides.
