Dragons Dogma Dark Arisen

This is almost a given if you plan on getting a couple of the other achievements (200, Sprinter, Hardened Veteran) but it is as simple as going through the story a second time. You don't have to change a single thing in how you play it: you can be as complete as you'd like or as minimal.

Just plunge that Godsbane blade in a second time and you'll get this one to pop.
