Split. The amphisbaena functions normally even if cut in half. If dealt a critical hit with a slashing weapon, the creature is cut in half and continues to function as two separate creatures, each with half of the original amphisbaena’s current hit points. The split amphisbaena can rejoin its two halves after completing a short or long rest. If one of the split creatures is slain, the amphisbaena can regrow the lost portion over the course of 1d4 + 2 weeks.
Actions
Multiattack. The amphisbaena makes one bite attack with each of its two heads.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or become poisoned for 1 hour.
