EDIT: I'm not saying that those two are the only better options, I'm saying it's hard to beat this bow. Also, while Shigeto does have a higher accuracy bonus, you do realise that this bow has more attack and DoT, right? Shigeto might be better, but not by much.
A much under rated bow imo, its no e-bow, but then again its about 2 million cheaper. I have actually out dmg another rng when he had e-bow and i had this one, using same ammo. So if you dont feel like spending 2+ million on e-bow or camp the NM, this is a good one, I used it til lv 71 then switched to Master Caster's bow (Beeing windy citizen)
