Orbus (5e Creature)
From D&D Wiki
Medium aberration, neutral
Antimagic Cone. The orbus’ 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 orbus decides which way the cone faces and whether the cone is active.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) piercing damage.
The orbus is only found among spacefaring beholders, lacking functional eye stalks and most of the intelligence of a regular beholder. They are the means by which beholders move their ships through Wildspace, channeling the energies of other members of the hive into motive force as a living Spelljammer helm. Aboard a ship, they tend to be found near the hive mother, who controls them, under the highest level of security available to them.
