Consecration

You reach your hand toward the sky in an attempt to call upon a Greater Power for aid. Your hand begins to glow with Divine Energy as you press your palm to the ground below you.

You create a 10ft Radius around you. Any Undead that enters the area for the first time, or starts its turn in the area, must make a Constitution Saving Throw. On a failed save, the creature has Disadvantage on Attack Rolls and Skill Checks while in the effected area.

At 5th level, this spell also effects Fiends. In addition, any creature effected by this spell who starts its turn in the area is subjected to the effects, as long as it remains in the area.

At 11th level, the Radius becomes 20ft. In addition, Attack Rolls and Skill Checks have Advantage against effected creatures in the area.

At 17th level, Undead and Fiends are effected by this spell when they enter the area and do not make a Saving Throw.
