Smelter Beast is an optional boss you can fight in BLACKSOULS 2, in a hidden part of the Fuming Forest area. Smelter Beast is a strong boss and after you take a certain portion of his health he will be on fire and even more dangerous with his attacks.
To get to the Smelter Beast go to the Fuming Forest, and then go behind the lava waterfall from the left side and go into the woods, that’s where you can find him.
By killing him you will be able to open the iron chest behind him which has the Claymore weapon inside.
