Purifier Ritual

Casting Time: 8 hours (must be performed at sunrise)
Range: 30 feet
Components: V, S, M (a sacred ember imbued with divine energy, consumed in the ritual)
Duration: Permanent

You sanctify a 20-foot-radius area, banishing all traces of necrotic corruption. Shadow-infused spells, undeath-based curses, and similar lingering magic are purged upon completion. The area becomes inhospitable to necromantic resurgence—necrotic spells cast within it automatically fail, and undead cannot be conjured, raised, or restored by any means short of divine intervention.
