You create an interdimensional link between two containers, both of which must be capable of being closed in such a way that their contents aren't visible. If both containers are left closed for 10 consecutive minutes, the contents of each one, totaling no more than 3 Bulk of nonliving, non-magical material per container, transport to the other's location.
If a container's contents total more than 3 Bulk, the transport fails. If either container is opened before the full 10 minutes have elapsed, the contents appear as they did when the containers were closed, and the process starts anew as soon as both containers have been closed. After the contents of the containers successfully swap, they can't swap again until after both containers have been opened at least once. Both containers must be located on the same plane for the process to function; if this ceases to be the case or if something else disrupts the effect during an active transposition, the process halts as if one of the containers had been opened.
Traits
An action with this trait requires a degree of mental concentration and discipline.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
Teleportation effects allow you to instantaneously move from one point in space to another. Teleportation does not usually trigger reactions based on movement.
