Callista

Detect Life. The banshee can magically sense the presence of creatures up to 5 miles away that aren’t undead or constructs. She knows the general direction they’re in but not their exact locations.

Incorporeal Movement. The banshee can move through other creatures and objects as if they were difficult terrain. She takes 5 (1d10) force damage if she ends her turn inside an object.

Wailing Wind. Callista's presence is signaled by a haunting wind. All creatures within 5 miles can hear her mournful cries, making Wisdom saving throws or suffering disadvantage on attack rolls, ability checks, and saving throws due to despair for 1 hour.

Legendary Resistance (3/Day). If Callista fails a saving throw, she can choose to succeed instead.

**Multiattack.** Callista makes three attacks: one with her Withering Touch and two with her Wind Scythe.

**Withering Touch.** Melee Spell Attack: +14 to hit, reach 5 ft., one target. *Hit:* 22 (4d10) necrotic damage.

**Wind Scythe.** Ranged Spell Attack: +14 to hit, range 120 ft., one target. *Hit:* 15 (3d8) slashing damage plus 9 (2d8) cold damage.

**Eternal Despair (Recharge 5-6).** Callista emits a devastating wail. All creatures within 300 feet that can hear her must make a DC 23 Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, with disadvantage if Callista is within line of sight, ending the effect on itself on a success.
