Some of the achievements are tricky to get. The story where you become a writer crosses over with the story where you become a fisher, but each version has a different ending based on where you started. So if you did the fisher story first, then the writer story, go ahead and go through the whole fisher story again, you'll find an alternate ending. Likewise, the pirate and dimensional travel stories crossover, so there's an extra ending to be had there once you've started as both the pirate and the scientist.
Alright, guys, I have a hint for you: Fireball murders seriously everything. Only play classes that give you Fireball. This includes Necromancer and does not include Paladin, not sure about others.
