Crawling Apocalypse

Rejuvenation. If the crawling apocalypse is destroyed, it's body reforms 24 hours later with all of its hit points and it returns to life. Destroying the crawling apocalypse or its corpse within the area of a hallow spell, a wish spell or similar magic can prevent this rejuvenation.

Multiattack. The crawling apocalypse can use cause Despair and makes two tentacle attacks.

Tentacle. Melee Weapon Attack: +11 to hit, reach 25 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage plus 10 (3d6) necrotic damage, and if the target is Huge or smaller it is grappled (escape DC 15). The crawling apocalypse transfers grappled targets to its arms. The crawling apocalypse has 6 arms, each of which can grapple one target. Until the grapple ends, the target is restrained, takes 10 (3d6) necrotic damage at the start of each of the crawling apocalypse's turns, and if it is a creature it must succed on a DC 14 Constitution saving throw at the start of each of the crawling apocalypse's turns or be cursed with mummy rot. The cursed target can't regain hit points, and its hit point maximum is reduced 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.

Cause Despair. Each creature of the crawling apocalypse's choice that is within 120 feet of the crawling apocalypse and aware of it must succed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature that fails the saving throw by 5 or more is also paralyzed for the same duration. 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 the crawling apocalypse's Cause Despair for the next 24 hours.
