I loved the premise and playing the adventure is fun, even for players that normally prefer making their own characters. I played this with some people with more knowledge of D&D than me, which was helpful but not necessary. However, if the players get to Dalterius, the speed is drastically decreased because they have to look up their new spells - which is why the last fight took way longer than it should've. I missed some details in the character sheet - especially Kevin misses his spells, which is a bit of a shame. I'd reccomend updating them to include proper spells for Kevin (and perhaps removing some typos). One of my players was very critical of the Mrs Banett build because it wasn't optimized (i.e. combination of Great Sword and protection style) but honestly, I like that these characters aren't as "meta" as the characters we usually play.

All in all, if you read the adventure well in advance, and have some players that enjoy a good plot twist and don't mind pre-made characters, this is really fun!
