You inscribe or mark a circle and seal it with your will. Until broken, the circle creates a thin, invisible barrier of abjurant force.

• Barrier: The circle blocks spirits, magically sustained creatures (such as summoned beings, ghosts, or necromantic constructs), and magical effects from crossing its boundary. Physical creatures and mundane objects move freely.

• Containment: Spirits or magically sustained creatures that begin inside cannot leave unless the circle is broken.

Breaking the Circle:
The circle is disrupted if—

• The caster moves more than 5 feet from the circle.

• The drawn line is smudged, broken, or covered by an object larger than a coin.

• Another creature deliberately scuffs or crosses it.

• The caster dismisses it voluntarily (no action).

• At sunrise, the circle erodes and collapses.
