Okay. Dex check 4. Is the guard's dex higher than a 14?
To hit 14. Pretty sure that's a good 'un. I've got quickstrike, so if drawing a long sword is appropriate I'll do that - otherwise I'll pull out my dagger and try to gut-shot the guard as we're going down.
Or cut off his ear. Or maybe just right in the eye - I'm kind of an opportunist here for the knifing and the jumping-on and all.
