Adds the element of the linked weapon (as flamethrower=fire,electro=lightning) to the atk or def of the part of the characters body the elemental upgrade is plugged into. For example, an arm with a flamethrower upg and an elemental link upg will do additional fire damage on punch attacks, and a torso with a Chem upg and an elemental link will first become more resistant to toxins, then, as the elemental link is upgraded, completely immune, and finally it will absorb every toxine damage it takes and turns them to HP. An elemental link upg linked with an offensive part of the body;upgrade will do more damage with every level it's upgraded.
