I've been working my way through Boss Mode for years now.... no, literally!
I'm stuck on Chapter 13. I'm not allowed to access Chapter 14, it's locked until I "beat the previous Boss Mode Chapter First."
I'm asking the community exactly what this means, because there aren't ANY chapters in boss mode where I've 3-starred every dungeon. In fact, other than maybe the first few chapters, most chapters have at least one or two (B) [ boss ] levels that I've never beaten. (especially levels that require select heroes.)
So, why suddenly is Chapter 14 continually locked? I spent the last few months powering up a light team hoping that beating the last dungeon in chapter 13 "The Untamed Tangle (B)" would unlock chapter 14, but today I finally got through it with 1 star and it didn't unlock anything.
The remaining dungeon in that chapter "Wriggling Weald" requires a reptile team, which is gonna take me FOREVER to power up. I don't want to invest that time in those characters if that's not the way to unlock Chapter 14.
Can someone please tell me what the specific requirements are? I read somewhere else that unlocking Boss Mode chapters requires beating all the same dungeons in regular modes, but Chapter 13 is fully 3-starred in both other campaigns.
Hope this question makes sense! Let me know any questions, and hopefully someone can give me some concrete answers.
Thanks in advance!
