I don't see any post on this, so here, please help us all out!
I'm rank 26 fisher and still using willow.. seems to be working ok.. but it's time to upgrade.
I found the recipe for the Bamboo Rod on YellowGremlin, finally gathered all 8 ingredients, mind you this was like a week ago now too, so some of the stuff (iron wire, antelope horn, nakki leather) were not extremely common. Bring all these materials to, at the time, my lv 20 carpenter friend.. and ... BAM.. "you cannot make anything with these materials".
If anyone comes across a recipe, or knows someone who has, please post it, or a link to it here! I'd love to have one of these, and can't believe they're not a part of the game already.
