Surge

As you focus your arcane nature into a piece of metal or conductive material you are able to send either a non-lethal and non-damaging surge of electricity through the length of the material within your grasp. 

If you have the feat Arcane Source Development I (Lightning) you can mold the properties of the metal you're sending surge through, though as your level in this specific feat levels up you can do more intricate things at first the most you can do is either cause a break, bend, or you are able to straighten a piece of metal twice per short rest.
