These are the best settings for using iDung in my opinion. I have used iDung for a long time now, and have experimented with the different settings, and I find that these bring the most xp per hour.
Did you start on floor 1 and Just do like 3 floors and Thats it?
Its not the settings fault You need to finish a prestige then yea..
Did you at least do a prestige before saying this?
