So my players have gotten it into their heads that they need to get to the Shard of Lust in Book 2 as fast as physically possible, and in so doing have skipped not only the warring tribes outside the Lady (which I made the consequences of that the Troglodytes were wiped out by the Boggards), but a LOT of rooms within the dungeon that could help them in the final fight against Ashamintallu, and to make it worse the Rogue snuck so far ahead that he got captured and taken to her, where she promptly Charmed him into more or less working for her.
With both of these factors in mind, as well as the knowledge that the Wizard will get massively dicked by the Dispel room for reasons that are too long to get into right now, I'm very worried that the fight against her will be too much and that Ashamintallu will win. If this happens, what would be the consequences? In addition to everything else, it's almost inevitable that they'll break the Curse on her, which I imagine would have an insane effect on her psyche since she's been warped by it for so long.
Any insight on this issue would be appreciated, thanks.
Update: we ran the session and due to a combination of their luck, skill, and 2 fudged die rolls on my end they won. Unfortunately I didn't get the chance to figure out what the ramifications of their actions would be since even though they knocked her down to just -1 HP exactly, there was a lot of arguing back and forth on what to do with her until one of them just decided to hit her while she was down and finished her off, much to the consternation of the ones that wanted to try and keep her alive and try to redeem her.
It is what it is, at least the players had fun overall.
Unfortunately between the two tribes, there's honestly not much reason to help either of them, at least at face value, and the group I was in no one wanted to help either of them. Only reason would be potentially to form a truce against the boggards, but it never happened.
