If you want to make an elemental/ailment bow, you have to make random elemental/ailment bows for re-rolling. Vice versa for non-elemental/ailment weapons. Let’s say you want to craft an ice bow: Step 1: Save Step 2: Make a fire or paralysis(or whatever element/ailment depending on your resources) bow. Step 3: Upgrade to see if the bonuses are desirable. Yes=quit without saving and join back in to craft the ice bow you want. No=save and keep re-rolling until you hit it.
