You draw magical energy through yourself as a conduit to recharge a magic item. A single magic item that uses charges and that you are touching at the time of the casting immediately regains 1d3 charges. An item cannot receive more than its maximum number of charges, and any excess energy dissipates harmlessly, unless the item in question is capable of a retributive strike. If such an item is charged past its capacity, it explodes as if you had used an action to enact the retributive strike, with all the resulting effects.
