Harpy Skeleton

CREATURE 5

MEDIUM EVIL MINDLESS SKELETON UNDEAD UNHOLY

A live harpy's song is compelling and captivating; a harpy skeleton's is anything but, rending the target's mind.

Almost any creature that had bones in life and leaves them behind in death can become a shambling, undead skeleton-humanoids, beasts, aberrations, fey, and more.

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed 20 feet, fly 40 feet

Melee Talon +15 (agile, unarmed), Damage 2d6+7 slashing

Melee Club +15, Damage 1d6+7 bludgeoning

Melee Club +15 (thrown 10), Damage 1d6+7 bludgeoning

Shriek (auditory, concentrate, emotion, fear, mental)

The harpy skeleton emits an unearthly, bone-chilling scream that deals 4d10 mental damage to all creatures in a 30-foot cone (DC 26 basic Will save). A creature that fails its save is Frightened 1 (or Frightened 2 on a critical failure).

The harpy skeleton can't Shriek again for 1d4 rounds.
