Anaconda

An immense river serpent that kills not with venom but with sheer crushing strength, looping coils around prey until it cannot breathe. It hunts from the water, striking and dragging in one motion.

Bite: piercing, melee 10 ft, +1 to hit, 1d10+4 piercing; on a hit the target is held. Constrict: control, while holding it crushes for 2d6 each round and the target cannot breathe until it escapes (save Dex Quick), cooldown 2 rounds.

Amphibious: swims at speed and breathes air and water. Camouflage: lies hidden in water or undergrowth until it strikes. Senses: Thermal Vision (60 ft), Keen Smell.
