Skorm's Bow is the strongest weapon in Fable. You can charge it infinitely, so you can kill many bosses in only a few hits with it. You can get it using this method before you even kill the Wasp Queen. In order to do this, you must do everything you can to be good. When you have 4 bars of goodness, go to the Chapel of Skorm with a mercenary. Wait until it is a quarter or so into night, and save. When it is midnight, you must sacrifice your mercenary (The sacrifice must occur AT MIDNIGHT, not the beginning of the sacrifice, so go slightly early). Skip all of the cutscenes. The person you spoke to should say something about how you will receive the evil you so desire, and you will get Skorm's Bow.
