With out spoiling anything, does this archetype work well for Shattered Star? It is designed for dungeon crawling, but somewhat specialized for constructs and undead.
Crypt Breaker
There are quite a lot constructs and there are some undead but not anything crazy (just about the amount of most APs).
While the d8 bombs vs constructs will definitely help, the d4 vs anything else and the fact that you have to pay for the mutagen with a discovery hurts.
I think that the archetype can work fine in this AP but don't expect anything crazy.
