Hello,
In the past it was possible to break up the battle tower challenge during ur walkthrough because if you fight 11 npc in a row it takes a lot of time and f.e u see smth in trade chat u cant buy it while u stuck in battle tower (cause all 11 fights takes a long time and no one wants to wait so long). So pls add that we can leave the battle tower during the challenge (between 2 fights of course)
