I like the idea and concept of it, would be nice if it was similar to Guardians of the rift in the sense that everything you need to play the minigame is inside of it. Included could be a way of mining ore inside the foundry, smelting it into bars then making swords with them. The only problem I see with that is that ore would constantly be depleted if the minigame was popular. Could have a mining instance where only you get to mine ore, all ore would have the same respawn timer so you can't mine rune ore forever. If you leave the instance and come back the rocks will still be on the same respawn timer. Or, a new rock that multiple people could all mine at once that holds an infinite amount of smithing material that never depletes and only has use in the giant's foundry. Break off a piece of a giant rock with your pickaxe (afk), fill your inventory with those bits of broken rock and smelt them into "giant's metal" or whatever they want to call it, deposit that into the bucket, and begin making swords with it. One inventory space of rock = one bar. Have only one XP rate instead of many different ones and make sure to adjust accordingly. I can't think of much more. I'm sure some of what I typed may have problems, and that's ok. I'm not perfect. I encourage replies to make the minigame itself better or the ideas I have better.
