Shepherd of Desolation

FEAT 12

Prerequisites Knight Reclaimant Dedication; Survivor of Desolation

You know how to keep others alive in the Gravelands' murkiest shadows. Allies within 10 feet of you gain the benefit of Survivor of Desolation. If you are a champion, this aura is a champion aura, even though you gained it from Knight Reclaimant instead of a champion feat or feature.
