The mind flayer doesn't require air, food, or sleep.
The mind flayer makes two Claw attacks or one Claw attack and one Tentacles attack.
Melee Attack Roll: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage plus 10 (3d6) necrotic damage.
Melee Attack Roll: +7 to hit, reach 5 ft., one creature. Hit: 7 (1d6 + 4) piercing damage, and if the target is a creature, it is grappled (escape DC 15).
