Hive Mother (5e Creature)
From D&D Wiki
Huge aberration, lawful evil
Saving Throws Int +11, Wis +9, Cha +11
Antimagic Cone. The hive mother's central eye creates an area of antimagic, as in the antimagic field spell, in a 150-foot cone. At the start of each of its turns, the beholder decides which way the cone faces and whether the cone is active.
Magic Resistance. The hive mother has advantage on saving throws against spells and other magical effects.
Multiattack. The hive mother makes 3 attacks with its bite.
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 28 (8d6+4) piercing damage. The target is grappled (escape DC 16) and the creature is restrained until this grapple ends.
Swallow. The hive mother makes one bite attack against a Large or smaller target it is grappling. If the attack hits, the target is also swallowed, and the grapple ends. While swallowed, the target is blinded and restrained, it has total cover against attacks and other effects outside the hive mother, and it takes 42 (12d6) acid damage at the start of each of the hive mother's turns. A hive mother can have up to one Large, two Medium, or four Small or smaller creatures swallowed at a time.
If the hive mother takes 30 damage or more on a single turn from the swallowed creature, she must succeed on a DC 14 Constitution saving throw at the end of that turn or regurgitate the creature, which falls prone in a space within 10 ft. of the hive mother. If the hive mother dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 15 ft. of movement, exiting prone.
The hive mother can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The hive mother regains spent legendary actions at the start of its turn.
Move. The hive mother moves up to its speed without provoking opportunity attacks.
Swoop (Costs 2 Actions). The hive mother moves up to half her speed then makes a bite attack.
A hive mother, also known as the ultimate tyrant or simply "The Ultimate," a title befitting of their pride, is a queen among beholders. They are twice the size of a normal beholder and always command a brood of these to do her will, using her innate telepathy to keep tabs on each of her subjects. These commanded beholders are always exactly identical to each other, as beholders do not tolerate differences in their species as a matter of principle, and all nearly identical to the hive mother, who is both larger and lacks the common beholder's eye stalks, with her eyes instead arrayed around the body itself.
While lacking the eye rays of a common beholder, hive mothers make up for this by their innate ability to command the beholders of her brood through a combination of innate ability and intimidation. It is not uncommon for a hive mother to threaten to eat a stubborn brood-spawn: an action she is wholly capable of carrying out, especially after the other beholder is deprived of its eye rays by her antimagic cone. Being consumed is also the regular fate of any spawn that turn out as "abominations," or in other words, even slightly different than the rest of the brood.
Though possible to find landside, the majority of hive mothers are found in wildspace, governing over a tyrant ship of her own, a construct that allows her to directly harness the power of her brood to devastating effect.
