Players constantly dying

[Fizban]

Anyone got thoughts on the Fortress of the Yuan Ti module?

I haven't checked it out, but I'd expect more of the same since it's the same adventure path. All you gotta do is look at the expected character level, then look at the ELs of the encounters, and how many extra problems the PCs have to deal with during those encounters. The newer format with all the encounters in the back makes it even faster. All the fix you should need is a bit of a sidequest to give them a level or two more than the module is advertising, and a reminder of all the bad stuff that happened last time (unless they're all soulknife monks now).

I'd let it be. Plus the nice thing about modules is that the difficulty is set so you don't have to worry about it being your fault. Except Google opinions to make sure the modules aren't sucky.

I mean, that's kinda my point isn't it? That the difficulty of this module is in fact faulty, so the DM should worry about it. Moudles aren't exempt from the same pitfalls as any other book. Overall internet opinions will probably be like overall forum opinions: lots of people saying it's great (because they player higher OP and need the challenge), and other people saying it's just a little difficult (because for them it was actually overpowered but they never considered the possibility a module would advertise the wrong PC level).

Since the medusa is gone, and the items of interest are gone, I'm assuming the portal that the medusa took to the Fortress is also now gone? Or was it permanent?

I'm sure you've already ruled on that in game (since the players came back to get their former selves, and presumably un-petrify themselves), but I might have introduced a reason/way that the portal is still there, but currently not working/blocked. Maybe a few side missions with Es'sarch to level up a bit, and get a means to breach through the blocked portal...
