Take out the strike part and make it only fire resist and I'll be all for it.
Desire + strike/counter is a very scary cycle.
I'll use G5 for these examples
1. You get hit. Strike is activated and the other person gets hit 173% of what they hit you with. Then desire activates because your strike hits them and they get hit an additional 82% of the 173%. So if both desire and strike go off, the reflected damage will be 315% of the original damage.
