Huh? The last I have of Lo Feng is him being at 79/99 health. Check that again, please. I no like killing my PCs.

Also, blasts usually can't deal precision-based damage. You'll notice that I characterized all the sneak attacks as either hands or feet made of stone. It's a Dai Li exclusive template called Grasp of the Dai Li. It also allows non-lethal damage.

Also, if you want to do something cool, awesome and/or plausible but impossible by RAW, go ahead and ask. I'll probably make a way for you to do it, though not necessarily an easy way.
