hard badge was really easy, just made my guy a poor warrior, trained him all the way as a horse stable boy to pay my way through schooling all the way in combat. made the dungeons simple.
Really easy, try to complete every level with two colors then 3 when you need to, and then move on to 4 if you have too its a good strategy. I only had to use 4 colors on half the levels.
