Copper armor kinetic blast

Copper armor could be a good middle ore for when the player goes from leather to Iron since copper is more abundant than iron. This could include a mechanic where the player could be struck by lightning in their Copper Armor, it could store the energy for a power attack later on that breaks the armor, yet kills the surrounding hostile mobs in a 3 block radius, creating a perfect early game balance with a unique purpose from the other armors. Each lightning strike could store a strike the equivalent of 1 tnt.
