Thieving from a Nature Rune Chest requires 28 Thieving, and each chest gives 25 experience upon looting. Once unlocked, these chests will lock themselves after 15 seconds. Players must right click and "Search for Traps;" failure to do so results in the player taking ⌊CurrentHitpoints×12100⌋+3 damage. The chest will always yield one nature rune and 3 coins when successfully opened.
