on subject of pixies, I can vouch that one good hit puts them out of the fight, you just have to hit them. My daughter runs a pixie in several con games and she has survived, though she has also taken assualt rounds and been dropped like a hot rock. her biggest advantage is that she is armed with shock frills, so most of the time its one hit, drop the foe.
on Canray..... think we need to find a way to get him in a running game
