Do you have the Endless Snackbag, Pump of Winds, Slime Crystal, and Bottomless Drink? You need all 4 to unlock the forge.
omg im so dumb, i dont have the bottomless drink, i had swell water thinking i had it lol so sorry
to make this not a waste of your time i did find a bug where you can leave the map right here where im standing at the spot where you have the nessie encounter
oh wow, i actually forgot to set the boundaries for the whole room. Better save inside the right spot, because it will be closed off next patch :)
