Multiattack

The ikuchi makes two attacks: one with its bite and one to constrict.

Bite

Melee Weapon Attack: +8 to hit, reach 15 ft., one target. Hit: 16 (2d10 + 5) piercing damage.

Constrict

Melee Weapon Attack: +8 to hit, reach 20 ft., one Huge or smaller creature. Hit: 14 (2d8 + 5) bludgeoning damage. The target is grappled (escape DC 16) if the ikuchi isn't already constricting two other creatures. Until this grapple ends, the target is restrained.

Crush (Recharge 4-6)

Each creature grappled by the ikuchi must make a DC 16 Strength saving throw, taking 23 (4d8 + 5) bludgeoning damage on a failed save, or half as much damage on a successful one.
