Map Sniffer

Collect every map in the game, and its the fiddly one. Most you buy or loot as normal, but one - the Map to the Old Mine #2 from Cor Kalom - only turns up if you're in the Swamp Camp and holding no map at all when you take that quest. That Swamp requirement clashes with your mage/Overachiever run, so treat this as a job for a dedicated Swamp playthrough and grab the Cor Kalom map before you pick up any other.
