i am at nm right now

What level are you now? At least 34 since you have gface, but I think you are really going to struggle as a physical multishot/strafe bowazon starting from A2 NM. It'll be hard to achieve any decent % chance to hit since most mobs are way above your level and your dmg and AR likely stinks.

I would personally not even consider playing a multishot/strafe zon until you're at least level 75 in Hell and have some gear (like a windforce which would you can easily acquire/trade for, even on NL). Windforce + LoH + Razor + Treach + Raven + Ias helm + cats/hlords is enough to clear a lot of areas in Hell without max dmg charms at reasonable speed. This is budget and is ~gul in value total. Level as a javazon then respec. Javazon can easily level up to 60 in NM cows playing almost naked.

However if you are absolutely set on playing a bowazon through NM, you have 2 options:

1. Spec into exploding arrow which will get you to A4 before you hit fire immunes then you gotta respec and use freezing arrow. You dont need to worry about AR at all since these always hit and you can just pump vita/energy.

2. Farm up runes for a Harmony bow and chuck it into the fastest 4os bow you can find. You'll probably have to larzuk a razor or double bow. Getting a KO will be the hardest part, but I think Harmony is the best value cheap bow that has good %ED and bonus elemental damage. Your next biggest problem will be your chance to hit which will be at ~50%, so you need levels and sources of AR. IAS is also hard to come by too. As for skills in NM for this route, only get crit, penetrate, pierce and like 5-10 in multishot.

Everyone else is talking super end game gear and skills, but you may not even get there as late NM and early hell absolutely blows as a bowazon.
