I will time compress, now that I know Raaze will not be coming down.
Round 664: The turtle dodges the flames (22 Ref save), but still takes 11-10=1 point of fire damage. The turtle has 126 HP remaining.
Round 667: Raaze breathes again, and the turtle dodges (natural 20), taking no damage. Raaze can breathe again in round 670.
A draw is declared at the end of round 669. Chaotic Evil curses the turtle's fire resistance and luck.
Round 670
A huge woolly rhinoceros trots into the arena to 55N60E, snorting and pawing the ground.
Next in round 670 for Chaotic Evil is a boneclaw (Monster Manual III).
