Why do Sameth and Maximus even need the Bad Luck Whammy? It doesn't seem to serve any purpose for the puzzles. I have already completed all four reels of Tomb of Sammun-Mak, and if I need it to slice the statue head in half, then couldn't that just as easily have been done by throwing the statue through the "Wrong Door," without the curse. Then again, I already had the curse on me before I threw the statue, so if I really needed the curse, than I didn't realize.
In short, why do I need the Bad Luck Whammy to complete the game?
