Graevrefalus Antimagic Spiritbound graevrefalus are immune to spells and magical abilities, with two exceptions. A negative spell or magical ability grants a spiritbound graevrefalus the quickened condition until the end of its next turn instead of its normal effects. A positive spell or ability makes a spiritbound graevrefalus slowed 1 until the end of its next turn instead of its normal effects.

Obliteration Beam [>>] (arcane, evocation, force) Requirements The spiritbound graevrefalus has bound a soul using its bind soul innate spell; Effect The spiritbound graevrefalus transforms the captured soul's essence into raw magical energy, channeling the spirit into a beam that deals 20d6 force damage in a 30-foot line (DC 38 basic Reflex save). The remaining fragments of the captured soul are released to the Great Beyond. The spiritbound graevrefalus can't use Obliteration Beam again for 1d4 rounds.

Paralyzing Force (arcane, incapacitation, necromancy) A creature damaged by the spiritbound graevrefalus's fist Strike must succeed at a DC 35 Fortitude save or become paralyzed for 1 round. On a critical failure, the creature is paralyzed for 1d4 minutes and falls prone.

Soul Binder When a spiritbound graevrefalus uses its bind soul innate spell, it binds the soul into its central crystal instead of the normal material component. The crystal can hold up to 60 souls. When encountered, a spiritbound graevrefalus's crystal typically contains 1d6 souls.

Soul Shriek [>>] (arcane, auditory, evocation, mental, sonic) The spiritbound graevrefalus emits a keening wail in a 15-foot cone that deals 16d6 sonic damage (DC 27 basic Fortitude save). A creature that fails its save is stunned 1, or stunned 3 on a critical failure. The graevrefalus can't use Soul Shriek again for 1d4 rounds.
