All future Spiteful Stormbolts will target this unit.
Casting and attacking builds stacks of Spite. At 5, a Spiteful Stormbolt arcs towards your current target, dealing X Nature damage over 3 sec.
Upon expiration the bolt returns, increasing the amount of Spite needed by 1 and permanently increasing Spiteful Stormbolt's damage against them until either of you die.
