Traits

Hold Breath. The ammit can hold its breath for 30 minutes.

Actions

Multiattack. The ammit makes two attacks: one with its bite and one with its tail.

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit:21 (3d10 + 5) piercing damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the ammit can't bite another target.

Tail. Melee Weapon Attack: +8 to hit, reach 10 ft., one target not grappled by the ammit. Hit:14 (2d8 + 5) bludgeoning damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be knocked prone.

Lore

Deep in the desert, far from the protection of the Hekma and the safety of Naktamun, lies a place called Ifnir, the Demons' Nest. The people of Amonkhet believe that the God-Pharaoh banished all the demons of this plane to the desolation of Ifnir as punishment when they rose up in rebellion against him. Some say that the angels carry the worst dissenters into the heart of Ifnir, which is a fate far worse than merely being abandoned amid the scouring sands.
