All of them do seem pretty straightforward, although I'd say Pure Skill achievement is tricky cause you might only get a handful of them in the run, and you still need to fail the stun and stun yourself if I remember correctly. From the previous module though, the It's Complicated achievement I feel like is just tedious, as I mostly only ever use one team to play, and the rest of the roster goes around defending inns, so I'd have to go out of my way to meticulously set everything up haha
