Fire Trap Spell
D&D Fire Trap Spell Description: Fire trap creates a fiery explosion when an intruder opens the item that the trap protects. A fire trap 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 5-foot radius around the spell's center. The flames deal 1d4 points of fire damage +1 point per caster level (maximum +20). The item protected by the trap is not harmed by this explosion.
