It can be a little convoluted, but if you look at "magic" "other weapons" and "bows" as a non-pro equation, maybe that helps? "Bows" modifies "other weapons", not "magic, and as it's also a weapon type, the correct syntax would look like this, essentially: m+(o^∞^-b)

Therefore, "weapons besides bows" or, the clunkier one (used "other" already), "weapons other than bows" would be a more betterly constructed sentence.
