Awktopot

Multiattack. The Awktopot makes three attacks: one with its bite and two with its tentacles.

Rows of Suckers. The tentacles are lined with two rows of suckers which attach to anything that touches them. A Medium or smaller creature adhered to the swarm is also grappled by it (escape DC 13).

Tentacle. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage plus 4 (1d8) piercing damage. If the target is Medium or smaller, it is grappled (escape DC 13) and restrained until the grapple ends. The Awktopot has two sets of 4 tentacles, each set can grapple one target.

Tentacle Slam. The Awktopot slams creatures grappled by it into each other or a solid surface. Each creature must succeed on a DC 14 Constitution saving throw or take 10 (2d6 + 3) bludgeoning damage and be stunned until the end of the Awktopot’s next turn. On a successful save, the target takes half the bludgeoning damage and isn't stunned.

Ten Tackles. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit 37 (10d6 + 2) bludgeoning damage, or 19 (5d6 + 2) bludgeoning damage if the swarm has half of its hit points or fewer.

Splash.     

If Awktopot takes damage it splashes boiling water from it’s pot, scalding for 1d6 +3 fire dmg.
