Fire trap creates a fiery explosion when an intruder opens the item that the trap protects. A fire trap spell can ward any object that can be opened and closed.
When casting fire trap, you select a point on the object as the spell's center. When someone other than you opens the object, a fiery explosion fills the area within a 15-foot radius around the spell's center. The flames deal 1d4+1 times [5/6/7/8/9] points of fire damage. The item protected by the trap is not harmed by this explosion.
You can use the fire-trapped object without discharging it, as can any individual to whom the object was specifically attuned when cast. Attuning a fire-trapped object to an individual usually involves setting a password that you can share with friends.
