Spell-Like Abilities (CL 12th)
Absorb Blood (Su)
As a swift action, the sayona may accelerate the blood loss of each bleeding creature adjacent to it. Those creatures take 1 Constitution damage each as the sayona absorbs their blood through its skin.
Living Form (Su)
As a standard action, a sayona can transform into a young, beautiful person for 24 hours. It can only use this ability if it has absorbed or drained blood in the past hour. In this form, the sayona has the aura of a living creature instead of an undead (for the purpose of life blindsight and similar effects), its fast healing increases to 10, positive energy attacks (such as the Harm Undead feat) deal half damage to it, and it cannot use its staggering gaze. Exposure to holy water or positive energy attacks in this form reduces the duration of this transformation by 1d4 hours.
Staggering Gaze (Su)
