This 10-foot long stone-colored lizard has a large, wide gaping maw filled with double rows of dagger-like teeth. Its head is large and flat and sports a ridge of hardened bone that runs the length of its head before tapering off near the middle of its back. Its four legs end in large, flat clawed feet.

If the gnasher lizard rolls a natural 20 on its attack roll, and subsequently confirms the critical hit, it severs the head of its opponent. This attack is effective on creatures up to one size larger than the gnasher lizard.
