Special Traits

• Feeder Arms. As a bonus action, the mooncalf transfers a grappled victim from a tentacle into its feeder arms. The escape DC for the feeder arms is the same as that for the tentacles. The mooncalf can make a bite attack against a creature grappled with its feeder arms as a bonus action.
• Life Sense. The mooncalf can detect the location of any living creature within 120 feet of it.
• No Breath. The mooncalf does not need to breathe.

Actions

• Multiattack. The mooncalf makes one bite attack and two tentacle attacks.
• Severing Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) piercing damage. In addition, if the mooncalf rolls a critical hit with its bite against a Medium or smaller creature, the target must make a DC 16 Constitution saving throw or have an arm or leg severed (50% chance of either). A creature that loses a limb in this manner suffers 7 (2d6) damage each round until another creature spends an action to staunch the bleeding with a DC 12 Wisdom (Medicine) check.
• Tentacle. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 8 (1d6 + 5) bludgeoning damage, and the target is grappled (escape DC 16). Until the grapple ends, the target is restrained and suffers disadvantage on Strength checks and Strength saves. The mooncalf can�t use the same tentacle against a different target.

About

Mooncalves are unearthly eyeless monstrosities that originate from the dark side of the moon, drifting across the airless surface. They inhabit the barren lunar landscape and can subsist on most forms of matter, even digesting rocks and gravel which they grind down with their incredibly hard, razor-sharp teeth, scooping up fodder with undulating tentacles and a throng of writhing, stubby appendages around their tooth maws.

Mooncalves gracefully float across the lunar wastes in small groups and while they find the heavier gravity of other planets more difficult, their alien biology still allows them to remain aloft. While a dangerous menace themselves, mooncalves often serve as scouts and foot soldiers for dominant overlords who rule the moon and the voids beyond space.
