Brainbill (5e Creature)
From D&D Wiki
Large beast, chaotic evil
Saving Throws Int +2, Wis +4, Dex +5
Telepathic Shroud. The brainbill is immune to any effect that would sense its emotions or read its thoughts, as well as to all divination spells.
Tadpole Gaze. When a creature that can see the brainbill's brain eyes starts its turn within 30 feet of the brainbill, the brainbill can force it to make a DC14 Constitution saving throw if the brainbill isn't incapacitated and can see the creature. On a failed save, the creature is stunned until the end of the brainbill's next turn. Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can't see the brainbill until the start of its next turn, when it can avert its eyes again. If the creature looks at the medusa in the meantime, it must immediately make the save. The brainbill is unaffected by its own gaze.
Multiattack. The brainbill makes three attacks: two with its beak and one with its talons.
Beak. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage.
Talons. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 14 (2d10 + 3) slashing damage.
The brainbill is a bizarre creation of some twisted people that resembles a walking bird with a mass of grotesque eyeballs instead of a brain. These eyes pulsate and cluster on the bird's skull, which is entirely open. They are actually tiny brains, each equipped with an ocular nerve and eye part as large as its lobe. The entire mass is protected by a viscous, clear jelly. The rest of the brainbill is rather average. It has the body of a large land bird, but with wings that are sufficient for flight. It uses its short, but stout, feet to run at high speeds and has a thick, hard beak, much like the axe beak.
Unknown Creation. The origin of the brainbill is rumored to be utterly disgusting, but the definitive narrative remains in debate. Some believe it to be a creation of the eldritch god Charylt. It is said that a sort of disease or parasite descends upon a typical axe beak or similar bird and rots out its brain, replacing the organ and the eyes with this pulsating, twitching mass. Others say it is pure mad experimentation that created this, similar to the research which bore fruit to the spider pig.
Disgust and Madness. The slimy mass of eyes on a brainbill has a bewitching effect on even the most stalwart of warriors. It has been known to drive weaker souls mad from its gaze. These eyes provide excellent sight for the brainbill. Combined with the strange jelly, the eye-brain has almost a psionic ability to see and sense thoughts as well as provide superb perception.
