Corrosive Touch. Any weapon(magical or non-magical) The Ooze That Eats the Heavens comes into contact with deals -1 damage until it is repaired. This can stack until -5, where the weapon breaks completely. Any melee weapon that rolls a natural 1 against it deals -2 damage and the user must make a DC 16 Dexterity save or it is lost inside the ooze.
Engulf. The Ooze That Eats the Heavens can occupy another creature’s space, and vice versa. A creature that starts its turn in the ooze’s space is subject to its Absorption. The ooze’s space is difficult terrain.
Absorption. A creature engulfed by the ooze, or hit by its slam attack, must succeed at a DC 16 Dexterity saving throw or become restrained for one minute. A creature that spends an action trying to remove the resin is entitled to another saving throw at the end of its turn. More than 20 points of fire or radiant damage on The Ooze That Eats the Heavens releases all absorbed creatures as its form destabilizes.
Legendary Resistance (3/Day). If The Ooze That Eats the Heavens fails a saving throw, it can choose to succeed instead.
Multiattack. The Ooze That Eats the Heavens makes two slam attacks, plus an additional slam attack against each creature within its space.
Slam. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage and 3d6 necrotic damage and the target is subject to Absorbtion.
Surge(recharge 5-6). The ooze raises itself up into a wave as tall as 50ft and surges forward 20 feet.
It Must Feed. The Ooze That Eats the Heavens is attached to a Holy Stone it is determined to feast on. Until the Power Towers are destroyed it focuses entirely on feasting and ignores any creature otherwise.
Power Tower. The Ooze That Eats the Heavens has 4 pillars of holy energy it is draining for power. Every turn, for every pillar that stands, the ooze regenerates 10hp. The pillars have 40hp and are resistant to all damage aside from bludgeoning, thunder, and force. The pillars deal 2d6 necrotic damage to any creature within 5ft when struck.
Corrupted Guardians. While the Power Towers are up, The Ooze That Eats the Heavens has a corrupted Ghostblade Eidolon (MOT, p222) guarding it for each Power Tower. The guardians can use Misty Step as a bonus action twice. They also regenerate 1hp every turn while their associated Power Tower is up and immediately dissipate if their Power Tower is broken.
No one knows where The Ooze That Eats the Heavens came from. All they know is that through some terrible happenstance, a force of corruption started feeding on a great amount of holy power. The Ooze That Eats the Heavens is only ever found feasting on a large holy power source such as a sacred stone, god spark, or any major relic of great power. By the times a party finds it, it has likely feasted to great amount, contributing to its gargantuan size, and has more than likely corrupted the forces meant to guard the power source it feasts on.
