ASTRAL FRED

Antimagic Cone. The dreadnought’s eye creates an area of antimagic, as in the antimagic field spell, in a 1-foot cone. At the start of each of its turns, it decides which way the cone faces. The cone doesn’t function while the eye is closed or while the dreadnought is blinded.

Demiplanar Donjon. Anything the dreadnought swallows is transported to a demiplane that can be entered by no other means except a wish spell or the dreadnought’s Bite and Donjon Visit. A creature can leave the demiplane only by using magic that enables planar travel, such as the plane shift spell. The demiplane resembles a stone cave roughly 10 feet in diameter with a ceiling 3 feet high. Like a stomach, it contains the remains of past meals. The dreadnought can’t be harmed from within the demiplane. If the dreadnought dies, the demiplane disappears, and everything inside it appears around the dreadnought’s corpse. The demiplane is otherwise indestructible.

Unusual Nature. The dreadnought doesn’t require air, food, drink, or sleep.

Multiattack Fred makes two claw attacks and a bite attack

Bite. Melee Weapon Attack: +5 to hit, one target. Hit: 12 (1d12 + 6) force damage. If the target is a small or smaller creature and this damage reduces it to 0 hit points or it is incapacitated, the dreadnought swallows it. The swallowed target, along with everything it is wearing and carrying, appears in an unoccupied space on the floor of the Demiplanar Donjon.

Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6+3) force damage.
