How it SHOULD work: your damaging Scorch spells have a 100% chance to cause your target to be vulnerable to spell damage, increasing spell critical strike chance against that target by 5% and lasts 30 sec. Stacks up to 5 times.

How it DOES work: It doesn't work. This effect doesn't stacks on target.
