Wall of Flesh

Great Wall. The Wall of Flesh completely takes up a 20x80 horizontal space and cannot turn directions, except through its legendary actions. The Wall of Flesh is also 40 ft tall. The Wall of Flesh can also move into creature's spaces that are Large or smaller, and, succeeding in a STR(atheletics) contest between them, can push the creature as it moves and deals 16(3d10)bludgeoning damage to them. If the creature wins the contest or if the creature is too big, it takes bludgeoning damage but the wall cannot go into the creature's space. If the Wall slams a creature against a wall, the creature takes 16(3d10) bludgeoning damage on the start of each of its turns as long as the Wall of Flesh stays in its space.

All-seeing. The Wall of Flesh can look in every direction without having to turn around.

Fear Aura. Any creature who starts its turn 60 ft from the Wall of Flesh must succeed on a DC 15 saving throw or become frightened of the Wall. Any frightened creature cannot escape magically via teleportation or melding.

The Hungry. The Wall of Flesh has 10 Hungry Tentacles. Each tentacle has AC 15, 45 hit points, and resistance to acid, cold, fire, and immunity to poison damage. If a tentacle is destroyed, it becomes a Hungry II under the Wall's control.
