Basic Power Cell

A basic power cell is a small, 3-inch, octagon that pulses with a faint, golden light. It is used to power some weapons and tools such as an antimatter rifle. It has AC of 5, immunity to lightning and psychic damage, and 4 hit points The cell has 10 charges, which do nothing on their own. If left in sunlight, the cell regains 1d4+1 charges every 4 hours. If the cell would take lightning damage, it instead regains a number of charges equal to the damage it would have taken. If it takes enough lightning damage to put it over twice it's maximum charges within 2 rounds, it overloads. Roll d20, if it is under 15, the cell does lightning damage equal to it's total charges+the excess damage to anyone touching it or a weapon it is attached to. It then drops to zero charges. If the roll is under 5, the cell also breaks.
