Round 670
A gargantuan, immensely fat, pearly gray dragon trots into the arena to 50N60E, opens its mouth, and lets loose a cone of force that is accompanied by a hurricane force wind. Sarlacc does not dodge the force (23 Ref save), nor resist the wind (16 Fort save). Sarlacc takes 85 points of force damage, and is blown out of the arena (unless wind is considered an air effect, but I do not think it is).
Two windghosts in TBoAA, two windghosts thrown out of the arena.
Next in round 670 for Lawful Good is Kepsektokiversvex the adult bronze dragon. He recognizes his opponent as an ethereal dragon, and knows its dragon traits, it has DR equal to his, and its breath weapon is a cone of force.
His spell keenness can be used on natural weapons, as long as they are slashing or piercing.
