here is the save to get the legendary achievement in overlord. took a lot longer than i thought just because i kept putting it off.
use the second save to go straight to the wizard. the armor is fully upgraded and i did it with the minions i have if you need more you can farm more on the path to the wizard or use the first save to farm in the dungeon but you are also going to have to beat kahn before you go to the wizard. if you download and like click the thank you button
You need both of the dlc pack raising hell pack and the challenge pack for this to work
