During the game I just jumped back and forth between game and BF to get the BF-merchants to reset their wares. But now that the game is finished and I'm playing Battlefields, that doesn't work. (Using the rift to go out and back in results in entering a new BF which means five-ten mins of loading... :/)
I tried entering a dungeon, killing two or three monsters and returning to the merchants. Inventory wasn't reset yet, though.
So what does it take for them to reset their inventory? Is it a certain amount of time to pass? Or do I need to level? Anybody knows?
