Boundary Sigil

You inscribe a temporary ward upon a door, window, container, campsite boundary, or other defined opening no larger than a 10-foot square.

Choose one function when you cast the spell:

• Warning: You receive a mental alert when a creature crosses the boundary.
• Revelation: The sigil emits dim blue light when an Invisible creature crosses it.
• Record: The sigil records the size and creature type of each creature that crosses it.
• Challenge: The first unauthorized creature crossing the boundary must succeed on a Wisdom saving throw or have its Speed reduced to 0 until the end of the current turn.

You can designate creatures as authorized when casting the spell.

At Higher Levels: When cast using a spell slot of 2nd level or higher, the duration increases by 8 hours for each slot level above 1st. At 3rd level or higher, you can select two functions.
