How to Unlock Fence Achievement
Get 10 orange items in exchange for the trophies in camp. You need to play as the Rogue to unlock this. Unlike the other two classes, the Rogue doesn’t get his equipment killing enemies. Instead, he gets trophies, that he exchanges for equipment once he reaches the camp tile.
The rarity of the equipment you get depends on the number of trophies you exchange, so keep doing loops and placing tiles like Spider Cocoons or Cemeteries to get as many trophies as you can in a single loop. You will need a little bit of luck, but with enough trophies, you will eventually get the 10 items. You can do this in the first boss so it doesn’t get too difficult.
