Corpsejaw

Adamantine Jaws. The corpsejaw’s bite works as if made of adamantine. The bite scores a critical hit on aroll of 19 or 20.

Keen Smell. The corpsejaw has advantage on Wisdom (Perception) checks that rely on smell.

Pounce. If the corpsejaw moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or fall prone. If the target is prone, the corpsejaw can make one bite attack against it as a bonus action.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage. If the corpsejaw scores a critical hit and the target wears nonmagical armor, the armor takes a permanent and cumulative −1 penalty to the AC it offers. Armor reduced to an AC of 10 is destroyed.

Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) slashing damage.
