OOC: I'll play the mivilorn. You do all the rolling.
A cross between a large elephant and a mastiff, 14 feet high at the shoulder and 18 feet long, enters the arena. It has a massive, oversized head with jutting, ragged teeth and loose skin on its jowls.
It charges to 95N10E, spewing digestive acid and then executing a charging bite maneuver. It will use its normal Power Attack = 15 to invoke massive damage.
