hmm, these were from the last time you asked… I haven’t tested Bows at all, but I think I might have to do that soon. you might have to do a Search 
for Bow and see what you can find for inspiration.
have you tried looking at some of these builds and making your own changes?
what floor are you up to? I’ve gotten a little over floor 2100 on M3, so if you are on a higher floor, you might be doing better than I am!
