You quickly disperse a circle of material that spirits find abhorrent—powdered silver or ground salt are popular choices. This forms a protective circle around you that spirits are loathe to approach, let alone cross. Any creature with the Spirit property that attempts to enter the circle must make a Charisma saving throw against your Spellcasting TN.

• Success: The spirit may enter, but the squares inside the circle are considered difficult terrain to the spirit.
• Failure: The spirit may not enter the circle, and cannot try again until the start of its next turn.

If you leave the circle, it immediately ends the spell.
