In my campaign the rogue pulled an amazing stunt with Erylium; he's a varisian and has a reinforced scarf.
Acrobatics check for a high jump, then he tried to wrap the scarf around her ankle. I let him try to trip the quasit out of the air with the scarf (she was visibile at the moment).
Natural 20. Quasit down, then all the party ganged up grappling the little b****, pinned her down (her CMD is 15) and finally the paladin impaled her on the ground (with smite evil)^__^
