Feat: Hallowed Necromancer Dedication
You've studied techniques allowing you to blend so-called hallowed necromancy into your own spellcasting to bolster the living and destroy the undead. You gain the Hallowed Ground focus spell. It costs 1 Focus Point to cast a focus spell. This feat grants a focus pool of 1 Focus Point that you can recover using the Refocus activity. You can Refocus by meditating or praying to connect yourself to conduits of vitality energy. Focus spells from the hallowed necromancer archetype have the same tradition as your spell slots.
Casting spells that create, heal, or otherwise aid or promote undead is anathema to you, as is cooperation with undead. Using void energy isn't anathema, as it serves a natural purpose, but twisting that void energy for creation is blasphemous to you. If you perform acts that are anathema to your principles, you lose access to all feats from this archetype. These abilities can be regained only with an Atone ritual.
