From D&D Wiki
Eater of Worlds
Huge undead, chaotic evil
Charge. If the eater of worlds moves at least 20 feet straight toward a target and then hits it with a bite attack on the same turn, the target takes an extra 4 (1d8) bludgeoning damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.
Legendary Resistance (3/Day). If the eater of worlds fails a saving throw, it can choose to succeed instead.
Split. If the eater of worlds is Medium or larger and it takes 10 or more damage in a single turn, it splits into two new eaters of worlds if it has at least 10 hit points. Each new eater of worlds has hit points equal to half the original's, rounded down. New eaters of worlds are one size smaller than the original eater of worlds.
Tunneler. The eater of worlds can burrow through solid rock at half its burrow speed and leaves a 10-foot-diameter tunnel in its wake.
Multiattack. The eater of worlds makes two melee attacks. It can replace one of these attacks with one use of its Swallow or Vile Spit.
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) piercing damage. If the target is a creature, it is grappled (escape DC 15). Until this grapple ends, the target is restrained, and the eater of worlds can't bite another target.
Swallow. The eater of worlds makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, that creature takes the bite's damage and is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the eater of worlds, and it takes 14 (4d6) acid damage at the start of each of the eater of worlds' turns.
Tail. Melee Weapon Attack: +8 to hit, reach 15 ft., one target. Hit: 7 (2d6) bludgeoning damage.
Vile Spit. Ranged Weapon Attack: +8 to hit, range 30/60 ft., one target. Hit: The target must make a DC 14 Constitution saving throw, taking 11 (2d10) poison damage and becoming poisoned for 1 minute on a failed save, or taking half as much damage and not becoming poisoned on a successful one. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
The eater of worlds 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 eater of worlds regains spent legendary actions at the start of its turn.
Attack. The eater of worlds makes one tail attack.
Conceived from the bottomless malice of demons, this mighty abyssal worm tunnels wildly to devour all in its path. Countless eyes cover its putrid flesh, and its head is only identifiable by the haphazard cluster of jagged teeth which serves as a mouth. The eater of worlds, true to its name, is a true omnivore, burrowing endlessly and devouring any organic matter in its path. It grows constantly and will occasionally split off segments of itself which eventually turn into foul new organisms, although they never grow into full copies.
The Eater of Worlds' Lair
The eater of worlds slowly spreads a rotten corruption to areas it frequents, turning the ground to dark craggy rock, infesting plants with sickness and decay, and making the area inhospitable for normal life. Instead, it populates the area with malformed copies of itself, budded off as it grows; scraps of flesh scraped off as it digs through stone may also take on a horrific life of their own. It leaves countless twisting tunnels in its wake, which it rarely leaves except in search of food.
The region containing the eater of worlds' lair is warped by the creature's corrupting presence, creating the following magical effects:
When the eater of worlds dies, these effects persist but can be removed through the use of the dispel magic spell or similar magic.
