Because the World Quest series 'The Chasm Delvers' and the Archon Quest Chapter II: Act IV run alongside each other and the achievements are obtained intermittently, they'll be included together in this post.
(The achievements in this section can be completed by just following through the Quest(s) itself as there's no choices/variations needed.)
