Amorphous. The zerxle can move through a space as narrow as 1 inch wide without squeezing.

Amphibious. The zerxle can breathe air and water.

Shapechange. The zerxle can use its action to polymorph into a Tiny or Small beast it has seen, or back into its true form. If it is in beast form, it reverts to its true form automatically when it attacks. Its statistics, other than its size, are the same in each form. It reverts to its true form if it dies.


Multiattack. The zerxle makes three melee attacks, but can use its bite and constrict attacks only once each.

Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 13 (3d8) cold damage.

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage plus 9 (2d8) cold damage.

Constrict. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage plus 9 (2d8) cold damage, and the target is grappled (escape DC 14). While grappled, the target is restrained, and the zerxle can’t constrict another target.

Empathic Innocence. The zerxle makes sounds and gestures that give the impression it is defenseless. All creatures that can see and hear it must succeed on a DC 15 Wisdom saving throw or refuse to attack it. Affected creatures feel a strong desire to protect the zerxle from danger. This effect is broken when the zerxle reverts to its true form. Undead and creatures immune to being charmed aren’t affected by the zerxle’s Empathic Innocence.
