It's really bow dependent. What are you using? I've finished hell with several frozen arrow / strafe hybrids. (Strafe for cold immunes, and to leach life and mana.) My best set up was Windforce as a primary bow, and Witchwild String on switch to use the normal Magic Arrow attack on cold / physical immunes. Not the fastest killer in the game, but safe and effective, and pretty darn good in the Pit.
im starting a new amazon however I saved the runes to make "edge" I just need to find a 3 socceted bow in normal that is worthy of all the hard work i put into producing that material ( many countess runs ) and muling for the 1st time ever. whats the lowest 3 soccett bow youd use for edge? Im glad I was being anal about putting it on and normal 3 socceted long bow becasue atleast i still have it in my mule account, but i still have the problem of finding the right bow to make my 1st rune word on. is there a lvl req for edge?
a really awasome guy gave me kuko shakaku once and i feel in love, where do those drop?
If you don't have ATMA yet, it's worth getting for the drop calculator alone. Kuko is a nice levelling bow, as is Ravenclaw. Skystrike is a personal favorite of mine through Nightmare, especially with the chance to cast Meteor.
I prefer to start with Strafe, and add the cold arrow tree after Normal, but that's just personal preference.
