King Tut
Ok, if the keypad thing doesn't go anywhere, I'll buzzsaw him.
Can I get some kind of bonus for chainsawing his face and/or tentacles? I mean it's right there in front of me. Haha you aren't going to believe this, I just rolled to see if I would hit and I was going to argue for a huge + to hit if I missed, and instead I roll the natural 20. That's right, BR: 20. For dmg, I get 4+4 = 8 * 2 = 16 pts of dmg. I'd also like to argue for a +dmg modifier, applied pre-multiple (naturaly!). I'll leave the rest in the DM's hands, and those of my fellow spelunkers.
Just in case the ruling is that I get a 2nd attack instead of +hit or +dmg, I BR 17, for 1+4 = 5 pts of dmg.
So to conclude:
I do 16 pts for sure, and if I get an extra attack due to his proximity and lack of defense, I get a hit for 5 pts.
Wait I just remembered, you said I can't attack. That seems weird, with the buzzsaw I don't have to dance around or swing or anything, I just stick my arm straight out in front of me...in fact, since he's standing right there (and in fact pulling himself towards me) I should do a hell of a lot more damage with a chainsaw. I could see being unable to attack with blunt weapons, since you need to generate momentum, but standing stationary against a buzzsaw is about the worst possible defense I can think of. If I can move my arm enough to fiddle with the control pad, I can move it enough to put the buzzsaw into the mind flayer's body/face/tentacles.
Thoughts/rulings?
