You lay the illusion of a trap over a lock or similar mechanism. As you perform the ritual, you can name creatures that are immune to this effect. These can range from specific individuals to members of broad categories, such as creature origin or type. A creature can discern the illusion if it succeeds on an Arcana check or a Perception check (DC 10 + your Arcana check modifier). Unlocking the lock, using the mechanism, or identifying the illusion discharges the ritual.
