Aqualisk

+6

The aqualisk can breathe air and water.

The aqualisk has advantage on saving throws against spells and other magical effects.

The aqualisk's weapon attacks are magical.

The aqualisk makes two attacks: one with its bite and one to constrict it. If it is grappling a creature, it can also use its Fling.

Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 29 (4d10+7) piercing damage plus 11 (2d10) force damage.

Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 33 (4d12+7) bludgeoning damage plus 11 (2d10) force damage, and if the target is a Huge or smaller creature, that creature is grappled (escape DC 17). Until this grapple ends, the target is restrained and the aqualisk can't constrict another target.

While on the ethereal plane, the aqualisk momentarily shifts to the material plane and makes a bite attack against a creature before returning to the Ethereal Plane. Unless the target can see into the Ethereal Plane, the aqualisk has advantage on the attack roll.

1/TURN

The aqualisk magically enters the Ethereal Plane from the material plane. If a creature is grappled by the aqualisk when it uses this action, the target must succeed on a DC 16 Charisma saving throw or be pulled into the Ethereal Plane with it. The aqualisk and target remain there as long as the aqualisk maintains concentration (as if concentrating on a spell). If its concentration is broken or it chooses to end its concentration, the aqualisk and the target both return to the material plane.

One object held or creature grappled by the aqualisk is thrown up to 60 feet in a direction it chooses and knocked prone. If a thrown creature strikes a solid surface, the target takes 3 (1d6) bludgeoning damage for every 10 feet it was thrown. If the target is thrown at another creature, that creature must succeed on a DC 17 Dexterity saving throw or take the same damage and be knocked prone.
