Also, about character building, I'm going off this guide: viewtopic.php?f=12&t=2901
So for my trait it said Dex and some vit, thats what i've been doing, Again my gear isnt the best but i'm willing to learn if you're willing to teach me how to improve

You need to smelt moar.

You need to smelt moar.

This, +40 at least, and don't add Vit so early on, you need the Dex for damage.

Edit for below: More damage basically. You get Momo after clearing Tiamat, but can only talk to him in town after reaching Yamataikoku.

Edited: I'm going to read up on more stuff ;w; (smelting etc)
And when do i get Momo(Dual sword partner) So i can stop questing and get grinding

Alright im getting the hang of this, already at +20, But now i need another weapon thats the same to upgrade that +20 even further,

Anybody have any tips in general?
