Desecrate

You desecrate the land through an unholy ritual. Choose a point within range. For the duration, the area within a 60-foot-radius sphere centered on that point becomes Desecrated.

Creatures have resistance to radiant damage and disadvantage on saving throws against spells that deal Necrotic damage while they are within the Desecrated area.

Features that Turn Undead automatically fail within this area.

Casting this spell on the same spot every day for a year makes this effect permanent.
