Ok for better dmg I suggest you start off by going for Wizaleon xtals at first. #1 they’re cheap, you can grind for the spina for them in less than a day. #2 they lower your mp cost a little (3 of them will give you -40% with moonlight) and as you probably already know, AR is very mp tolling, so every little bit helps.
The next thing you should do is start building up your bow collection, namely elemental ones. This is the best way to raise AR damage but also expensive
(Scroll down to find the color coded list:
irunaonline.boards.net/thread/17184/list-bows)Start with just getting the beginner ones, trust me just having the element is much better than having the best type of bow at first.
On to atk% or crt dmg. Well for now if you’re going to purely AR spam, crt dmg is pretty worthless to you (unless you have hide attack *—*) if you do happen to have hide attack, the best damage comes from a balance of atk (base), crt dmg% (first multiplier), and elemental dmg (second multiplier). In the future when you get Area rain and Cross fire however, cross fire is affected by crt dmg so you’ll need it then.
Ok last one Adamantite... for now I’m sure there are stronger specs, mq+wol for instance, but don’t waste your spina, they’ll only be temporarily better. Adamantite arrows/thimble are by far the best late game (even ns compared to a slotted spec)
Oh just wanted to add real quick, the more Dex you have, the higher your hit rate and thus the higher consistent dmg you have so try making Dex as well
