Problem Solver Achievement
Clear 70 sub-quests. No request from the people is too hard for this party to solve.This achievement is for completing all 70 subquests in the game. None of them are missable and can be completed at any time, including after completing the story (some aren't even available until after the story is complete). See the guide HERE for a complete list of all the subquests and how to complete them. Bear in mind, you need to collect all the owls for one subquest, and all the artifacts for another to even spawn. See those related achievements for more help.
