Flavor

A closeable object is warded so that opening it without the password bursts into a ring of fire.

Mechanics

Wards a closeable item (chest, door, book) within touch; unauthorized opening triggers a fiery burst dealing 1d4 + 1/caster fire in a ~5-ft. radius ( vs. spell for half). The priest and those told the password open it safely. Permanent until triggered/dispelled. Takes time to cast. : a half-pound of gold dust (~$$) and the holy symbol.
