Bri-gade Squid Devil

Fear Aura. Any creature hostile to the squid devil that starts its turn within 20 feet of the squid devil must make a DC 21 Wisdom saving throw, unless the squid devil is incapacitated. On a failed save, the creature is frightened until the start of its next turn. If a creature's saving throw is successful, the creature is immune to the squid devil's Fear Aura for the next 24 hours.

Spider Climb. The Squid Devil can traverse walls and ceilings with its tentacles, as though affected by the spider climb spell.

Magic Resistance. The squid devil has advantage on saving throws against spells and other magical effects.

Magic Weapons. The squid devil's weapon attacks are magical.

Waterbreathing. The Squid Devil can breathe underwater.

Innate Spellcasting. The squid devil's spellcasting ability is Charisma (spell save DC 21). The squid devil can innately cast the following spells, requiring no material components:

At will: detect magic, fireball, create food and water

Multiattack. The squid devil makes four attacks: one with its tentacle, one with its claw, and two with its ladle.

Tentacle. Melee Weapon Attack: +14 to hit, reach 30 ft., one target. Hit: 22 (4d6 + 8) bludgeoning damage. The target must succeed on a DC 21 Strength saving throw or become grappled. At the end of each of the Squid Devil's turns, each hostile creature grappled in this way takes 21 (4d6) piercing damage at the start of each of its turns. The grappled creature may use its action to repeat its saving throw. If the tentacle holding the player took damage, they may make this saving throw at advantage.
