I had a long ranting review and it timed out, so now I'm may be extra salty...
I'm gonna summarize.
Party: Summoner 7 (me), Rogue 9, Gunslinger 7, Arcanist 7
Upper Tier 4 Party Adjustment
Breaches: The scenarios breaches mechanic punishes players for making sensible calls. The PCs don't know about breaches. In the Library, the players aren't aware that they are causing breaches when they fail by 5 or more. So a party only thinks that failing is only costing them time and the goal is to get all the books before the 6 rounds are up. More so, they get breaches for killing the ridiculous dragon who tried to kill them moments earlier. In fact, not only do they get breaches, they plummet 90ft after a CR 11 fight. It's a hidden mechanic that punished players onto of punishing players.
Will Save or Bust: The gimmick of the scenario is to overload the party with more saves than they can possibly make. This is the most frustrating part of the entire thing. "Made 4 will saves in a row? Have another? Failed? Stunned for 4 rounds." It's the equivalent of the guy in an arcade fighting game who holds down and presses the kick button, but instead of dealing damage it makes you unable to play your character each time you're hit. It's frustrating and there isn't much to be done about it beyond get a better will save.
There are a few other things I would touch on but I would avoid this one. The rewards are good, but the scenarios is terrible and unfun in my opinion and I think I've only said that about one other scenario.
