Two Worlds

Pretty self-explanatory, but if you put any decent amount of time into doing side quests, this should be a breeze. For the sake of giving a measuring stick, I reached level 35 having only found the first relic stone in the King's Tomb. I would guess I've only completed 75% of all side quests that I've come across thus far. (some failed do to helping Clan Karga prematurely) I've split my time fairly evenly between doing quests and wandering to find locations towards that achievement, killing everything and anything that crosses my path.

A few freezing issues cost me some progress, but I would gauge that I popped this around the 15 hour mark of play time.
