It would be a good idea to set up enough dungeon brick to block off your current corruption, because after you go into hardmode, it will spread like crazy. (I spent an hour trying to reclaim my desert!) Also, adding lava traps or any other trap system would be a good idea because your first few nights in hardmode will be fairly hard. Good luck on killing the WoF~
