Astral Claimed

The Astral Claimed is an extraordinary feat granting adventures with a species originating from the astral plane (exp; Astral Elf or Lunar Dragonborn) a profound connection with the Astral Plane after living in the Astral Plane for one year, catalyzing their existence with cosmic unpredictable energies. Those who bear this feat are marked by the Astral energy; their soul becomes a beacon within the ethereal currents, establishing an unbreakable tether to the Astral Plane. This mystic bond yields uncanny abilities that bend the fabric of reality across planes, allowing them to phase through existential barriers and perceive the unseen threads connecting the planes
