>>41760218Shelmet's shell does absolutely nothing because it is just a shell.Being exposed to the energy that comes from trading with Karrablast transforms and strengthens the shell into metallic armor. When Karrablast steals Shel,et's shell, it is treated as a pseudo held item, and that item binds to Karrablast via the trade energy much like how a Metal Coat binds to Scyther, changing its type. Shelmwt's shell is part of its physiology and is unaffected by the energy.
