Head graze should have a random chance to kill the target

[NobleWinter]

Graze means to touch lightly in passing and not a direct hit. The icon of the action also reflects this.

In the midst of a hectic battle it seems fairly likely a skilled marksman would inadvertently make a solid head shot instead of a minimal graze that's just enough to get to caster to stop chanting without doing any damage. A 1% chance to kill minor enemies would just be fun. It's not like we get much use out of the skill in general as I rarely ever see a cast bar it applies to.
