These 20 ft crocodiles have muscular frames and powerful bites. On a natural hit roll of 19-20, a giant crocodile goes into a death roll, dragging the target into the water and rolling over repeatedly to disorient and drown the prey. Each turn, the target must make a Luck (Dex) save or lose its action. A successful check means the character has broken free and may act normally. Giant crocodiles often wait beside the edges of waterways, fully submerged but for their nostrils, before ambushing their prey.

A Kronosaurus is essentially a colossal 40 ft dinosaur crocodile with fins instead of legs. They have 16 HD, Bite 3d12 and Off Turn Attacks.
