The gnome replies; "Well, no much use of a battery as you can just go dungeon hour and recharge the item that way. Overall storing mana on artificial vessels from dungeons does not work that well, as the energy fades from items quickly as dungeon goods. Only where it lasts longer is in people and some people can get mutated and affected by the dungeon energies. Especially people living near or around the dungeon get affected."<br/><br/>OOC: Roll investigate if want see what else is there among trinkets/toys more practical or interesting items.
