How would you fix raventomes??

Prove they need "fixing" first.

The refine can have TA built into the weapon, so it can open the A slot for other skills like Fury/LnD or something.

I don't think they need fixing. I agree with Disgusting, TA would be nice for a refine, but other than that they don't need 'fixing' since nothing is really wrong with them.

Bladetomes should get a refine that gives them Bold Fighter

I have some ideas, at least for unique ones. Mind if I make a seperate post?

edit: aaand done

They do exactly what they were designed to do, I don't think they need a refine.

I don't think they're underpowered or anything, but I think it wouldn't hurt to give them the stat-boosting refines some of those generic weapons have (+1 atk, +2 spd, +3 def/res)
