No, he hasn't started running, and some of you might have even acted before the spell, if not for the Partial successes.<br/>After all, you can't spot only half of him, but it might take a bit longer than expected ;).<br/><br/>He's still evading at a -5, no penalties for darkness, but a small target. It's small and not quite close, but he doesn't expect you to aim for it, so this cancels the distance. Make that -8 to hit him.<br/><br/>The pig-sticker is a normal big knife, except its DR is 1 higher than a knife, and it's very obviously optimised for slashing, not stabbing.
