change daemon

always changing(4/Day). If the daemon fails a saving throw, it can choose to succeed instead.

Unusual Nature. The daemon doesn’t need food, drink, or sleep.

Multiattack. The daemon makes one Parasitic Tentacle attack or uses Spellcasting. The daemon also uses Psychic Whisper twice.

Parasitic Tentacle. Melee Weapon Attack: +9 to hit, reach 10 ft., one creature. Hit: 25 (6d6 + 4) piercing damage plus 25 (6d6 + 4) necrotic damage. The target must succeed on a DC 17 Constitution saving throw or be poisoned. The poisoned target can repeat the save at the end of each of its turns, ending the effect on itself on a success. The third time the target fails the save, the target dies and dissolves into a gibbering mouther that obeys the daemon and uses the target’s initiative.

Psychic Whisper. The daemon targets one creature it can see within 120 feet of itself. The target must succeed on a DC 17 Wisdom saving throw or take 25 (6d6 + 4) psychic damage and be stunned until the end of the lich’s next turn as incomprehensible whispers fill the target’s mind.

Spellcasting. The daemon casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 17):

At will: detect magic, mage hand, prestidigitation

2/day each: dispel magic, hunger of Hadar, lightning bolt

1/day each: arcane eye, dimension door, plane shift (self only)

Far Realm Step. Immediately after taking damage, the daemon, along with any equipment it is wearing or carrying, magically teleports up to 60 feet to an unoccupied space it can see.
