[Spell] Circle of Protection: Draw a circle on the ground, up to 10 feet in diameter. Creatures from a different plane of existence than the current one can't enter the circle unless you allow them. The spell ends when you leave the circle, and breaks if a creature from a different plane of existence attempts to cross the circle after a character smudges or alters it.
[Spell Modifier] As long as you have a warding spell active, you have +1 armor.
