Is there any way to access the Doomforge other than through the Arbaziloth's room?

Question

I noticed that on one of the floors of the Castle Catacombs of Azzilon there is an inaccessible orange portal. Is there any way to use it to access the Doomforge? Or is there another way that doesn't require killing Arbaziloth on hard mode?

Answer 1

No, so far it is not possible to access the forge without killing Arbaziloth in hard mode
