Traits

Amphibious. The chuule can breathe air and water.

Sense Magic. The chuule senses magic within 120 feet of it at will. This trait otherwise works like the detect magic spell but isn't itself magical.

Actions

Multiattack. The chuule makes two pincer attacks. If the chuule is grappling a creature, the chuule can also use its tentacles once.

Pincer. Melee Weapon Attack:  + 20 to hit on hit 12d10 piercing damage, and the target is grappled 

Tentacles. One creature grappled by the chuul must succeed on a DC 13 Constitution saving throw or be poisoned for 1 minute. Until this poison ends, the target is paralyzed. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
