Okay, I hope this one is easy to answer: how am I supposed to use Dual Pistol Execution? It requires my target to be stunned, but (unless I'm just blind) I can't find anything in the that tree or my other tree (Karate) that causes stun... unless it's something that's not listed in the skill description.
Of course, I don't want to be forced to switch trees, but I at least want to see what Dual Pistol Execution looks like. I thought my other lv. 46 skill (Ki Charged Leg Sweep) was going to be hard to get working, but it's actually pretty easy as long as my target stays alive long enough... turns out DPE is the one that's causing me headaches
