Crawling Apocalypse

Aura of Despair Each creature of the crawling apocalypse's choice that is within 120 feet it and aware of it must succeed on a DC 14 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the crawling apocalypse’s aura of despair for the next 24 hours.

Regeneration. The crawling apocalypse regains 10 hit points at the start of its turn. If the crawling apocalypse takes fire damage, this trait doesn't function at the start of its next turn. The crawling apocalypse dies only if it starts its turn with 0 hit points and doesn't regenerate.

Unholy Toughness A crawling apocalypse gains a bonus to its hit points equal to its Charisma modifier when hit dice are rolled.

Multiattack A crawling apocalypse makes two tentacle attacks.

Tentacles. Melee Weapon Attack: +9 to hit, reach 40 ft., one target. Hit: 21 (4d6+5) bludgeoning damage plus 14 (4d6) necrotic damage. If the target is a creature, it is grappled (escape DC 14). Until this grapple ends, the target is restrained, and the octopus can't use its tentacle. Additionally, the target must succeed on a DC 14 Constitution saving throw or be cursed with mummy rot. The cursed target can't regain hit points, and its hit point maximum decreases by 10 (3d6) for every 24 hours that elapse. If the curse reduces the target's hit point maximum to 0, the target dies, and its body turns to dust. The curse lasts until removed by the remove curse spell or other magic. Each round the target is grappled, they must roll their save for mummy rot until they fail or they escape.
