  • Hold Breath. The demoncroc can hold its breath for 30 minutes.
  • Shapechanger. The demoncroc can use its action to polymorph into a six-foot-long carp. Its statistics are the same in each form.


  • Multiattack. The demoncroc makes one Bite Attack and one Tail attack.
  • Bite. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 21 (3d10 + 5) piercing damage, and the target is grappled (escape DC 19). Until the grapple ends, the target is restrained, and the demoncroc can’t bite another target.
  • Tail. Melee Weapon Attack: +9 to hit, reach 10 ft., one target not grappled by the demoncroc. Hit: 14 (2d8 + 5) bludgeoning damage. If the target is a creature, it must succeed on a DC 17 Strength saving throw or be knocked prone.


The demoncroc swims the layers of the lower planes devouring demons, devils, and any other creatures that cross its path. Purportedly it can swim the River Styx without suffering the memory loss effects of said waters.

The demonic spirit inhabiting this form is bloodthirsty and malign. At night, it causes the demoncroc to come forth and stalk through the village seeking prey. Its weight and strength allow it to smash down doors in order to get at victims; however, it can’t climb stairs.

This demon crocodile is some 30 feet long and five feet broad.
