Once the metal that Eisen put into the forge properly heated up, the old man started to properly beat it into shape to turn it into the parts that he needed to be metallic. For one, that was the actual shotgun barrel, and then there was also the part that the actual shotgun shells were placed into. Of course they wouldn't be actual shotgun shells, but rather, Eisen would give Dentex a couple of mana-batteries that he could replace whenever he wanted to. So he could have a pack of a dozen small mana-batteries, have ten of them filled up at all times and constantly replace the 'ammunition' inside of the shotgun-staff.
