Holy Ground
Level 5 · Evocation · Ritual · Concentration
You invoke divine powers to bless the ground within 60 feet of you. Creatures slain in the affected area cannot be raised as undead by magic or by the abilities of monsters, even if the corpse is later removed from the area. Any spell of 4th level or lower that would summon or animate undead within the area fails automatically. Such spells cast with spell slots of 5th level or higher function normally.
