This is the most basic spell for recharging energy for conjured items. It is capable of recharging only one item and even then it is usually not powerful enough to recharge to full power with just one casting when item is severely depleted. So it may be quite challenging task to keep all your conjured items in full power during some furious battle and you may find yourself losing some of your conjured items here and there due to energy running out.
