Amenopophis, The Flayed God

Magic Resistance. The mummy lord has advantage on saving throws against spells and other magical effects.

Rejuvenation. If destroyed but left near a functioning Loom, Amenopophis gains a new body in 24 hours.

Spellcasting. Amenopophis is a 10th-level spellcaster. His spellcasting ability is Wisdom (spell save DC 17, +9 to hit with spell attacks). He has the following cleric spells prepared:

Cantrips (at will): sacred flame, thaumaturgy

1st level (4 slots): command, guiding bolt, shield of faith

2nd level (3 slots): hold person, silence, spiritual weapon

3rd level (3 slots): animate dead, dispel magic

4th level (3 slots): divination, guardian of faith

5th level (2 slots): contagion, insect plague

6th level (1 slot): harm

Multiattack. Amenopophis can use his Dreadful Glare and makes one attack with its flaying fist or whirlwind.

Whirlwind. Area Attack. Amenopophis uses his wings in a whirring, spinning motion. All creatures within 10' must make a DC 16 Dex saving throw, taking {"diceNotation":"3d6+4","rollType":"damage","rollAction":"Whirlwind","rollDamageType":"bludgeoning"} damage and be knocked prone, or half as much damage on a successful save. Recharges 5-6.

Flaying Fist. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 14 (3d6 + 4) bludgeoning damage plus 21 (6d6) necrotic damage. If the target is a creature, it must succeed on a DC 16 Constitution saving throw or receive the Curse Of The Flayed God. The cursed target can't regain hit points, and its hit point maximum decreases by 10 (3d6) for every 24 hours that elapse. As the curse progresses, the target undergoes a horrible transformation. Its flesh slowly sloughs off, leaving the creature still alive but disfigured. If the curse reduces the target's hit point maximum to 0, the target is transformed into a spectre, and its flesh is turned into Thread for the Loom. The curse lasts until removed by the remove curse spell or other magic.

Dreadful Glare. Amenopophis targets one creature it can see within 60 feet of it. If the target can Amenopophis, it must succeed on a DC 16 Wisdom saving throw against this magic or become frightened until the end of Amenopophis's next turn. If the target fails the saving throw by 5 or more, it is also paralyzed for the same duration. A target that succeeds on the saving throw is immune to the Dreadful Glare of all mummies and mummy lords for the next 24 hours.

Amenopophis 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. He regains spent legendary actions at the start of his turn.

Attack. Amenopophis makes one attack with his flaying fist or uses his Dreadful Glare.

Blasphemous Word (Costs 2 Actions). Amenopophis utters a blasphemous word. Each non-undead creature within 10 feet of him that can hear the magical utterance must succeed on a DC 16 Constitution saving throw or be stunned until the end of the mummy lord's next turn.

Channel Negative Energy (Costs 2 Actions). Amenopophis magically unleashes negative energy. Creatures within 60 feet of him, including ones behind barriers and around corners, can't regain hit points until the end of Amenopophis's next turn.
