Vengeful Spite [R] (evocation, occult) Trigger A foe critically hits the banshee, or the banshee critically fails their save against a foe's damaging effect. Effect The banshee lashes back at their tormentor, dealing 4d10+14 mental damage (DC 38 basic Will save) and applying the effects of terrifying touch based on the results of the same Will save.

Spectral Ripple When a banshee Strides at least 10 feet, they're concealed until the start of their next turn.

Terrifying Touch (emotion, enchantment, fear, occult) A creature damaged by the banshee's touch that isn't already frightened must attempt a DC 38 Will save (DC 43 if the attack was a critical hit). If the creature fails its save, it's frightened 2; on a critical failure, the creature also cowers with fear and is stunned 4. If the creature is protected against fear by a spell or magic item, the banshee's touch first attempts to counteract the protection effect, with the effect of a 9th-level dispel magic spell.

Wail [>>] (auditory, concentrate, death, necromancy, occult) The banshee unleashes a soul-chilling wail of the banshee (DC 38). This Wail overcomes silence and similar effects of 5th level or lower. The banshee can instead use Wail as a three-action activity to overcome such effects of up to 8th level. The banshee's Wail resonates for 1 round, and any creature that comes within the area during that time must attempt a save against the effect. A creature can't be affected more than once by the same Wail. The banshee can't Wail again for 1d4 rounds.
