We now have a fantastic new guide submitted from JAC super player Hyper Emerson that shows the locations for all 33 of the invisible stat icons strewn about the NG+ run of the game.
Check it out along with the previous Prayer and Equipment guides when you get a shot, and be sure to vote for it as the best guide of all time!

Got a good idea for your own guide to the game you'd like to see immortalized in the STEAMINESS to STEAMITUDE? It's all hands on deck and anyone's game so I say: Go for it!
