I think it wise that we put this device to the test before you commit fully to your delve down into the darkness of the Crypts. Take the torch to the edge of the magical darkness and activate it. See if it serves its purpose and provides illumination, and more importantly, discern how it behaves when exposed to this magic. This totem was bound with a specific purpose and should be compelled to adhere to that purpose, but there's no real telling until we get there and test this hypothesis.
