Secret Room in the Tavern:
Once you defeat the final boss on any difficulty, a neon sign will light up on the second floor of the Tavern–an OPEN sign above a closed door. If the sign is lit up, walk into the door and you will enter a secret room. There is 10K mana inside, along with four unique weapons, one for each class, and a Secret Stash that acts like a normal forge.
