Cascade

Launches a Holy bolt at the target that grows in power as it travels, which causes ${*0.4} to Holy damage to an enemy, or ${*0.4} to healing to an ally.

This effect can bounce from allies to other allies, or from enemies to other enemies. Each time it bounces it will split into 0 bolts, preferring farther away targets, and never hitting the same target twice. Cascade can bounce up to 0 times.
