Crocodile

A patient armored reptile that floats like driftwood at the water's edge, then explodes into motion to drag prey under and drown it. Most who see one clearly are already in its jaws.

Bite: piercing, melee 5 ft, +1 to hit, 2d8+4 piercing; on a hit a Large or smaller target is held. Death Roll: control, while holding it rolls and drags the target underwater, dealing 2d6 and drowning it on a failed Dex Quick save, cooldown 2 rounds.

Amphibious: breathes air and water. Hold Breath: lies submerged and motionless, indistinguishable from a sunken log. Senses: Night Vision (60 ft), Vibration Sense (feels movement, water vibration, 30 ft).
