Defeating Inkerton without taking damage (either health or shell damage). There were only a few attacks that felt comfortable to get in some swings afterwards, notably after he fires his gun, which is why I didn't feel as eager to use scrap hammer here.
There's also some odd stuff that can happen if he gets positioned by the bones or directly hit by his gun. The gunshot also doesn't appear to hurt you at all if you're far enough away.
