Multiattack. Urphania makes three attacks with her claws.

Claws. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 21 (3d8 + 6) slashing damage plus 7 (1d12) acid damage.

Fey Blast. Ranged Spell Attack: +14 to hit, range 250 ft, 1-4 targets. Hit: 13 (1d10 + 7) force damage. If a target is hit by a beam of fey blast they are knocked backwards 10 ft.

Invisible Passage. Urphania magically turns invisible until she attacks or casts a spell, or until her concentration ends (as if concentrating on a spell). While invisible, she leaves no physical evidence of her passage, so she can be tracked only by magic. Any equipment she wears or carries is invisible with her.

Frightening Presence. Urphania's appearance is so horrific that it is repulsive on a supernatural level. Anyone creature who sees Urphania must make a DC 20 wisdom save or become frightened of her for 1 minute. At the end of each of these creature's turns they may retake the save. If a creature succeeds on this saving throw they are immune to Urphania's Frightening Presence for 24 hours.

Dark Delirium (Recharge 5-6). Urphania can plunge a creature it can see within 60ft  of it into an nightmarish landscape. They must make a DC 24 Wisdom save or become frightened or charmed by her for 1 minute or until concentration ends/the effected creature takes damage. Until this illusion ends, the creature thinks it is lost in a misty realm, the appearance of which you choose. The creature can see and hear only itself, Urphania, and the illusion.

3/round.
