Sepia Snake Sigil

Much like the symbol spell, this spell allows you to protect an object or location from intruders. Unfortunately, you can’t program it to let anyone (though it won’t attack the caster), so it finds less use in populated strongholds. Its best feature is its ability to capture an intruder alive and keep her in suspended animation until you figure out what to do with her.

Casting: 650 gp (Wiz5) or 680 gp (Sor6) or 710 gp (Brd7)
