Finding Mythril Weapons

[Kawaii Ryûkishi]

Is there any reliable way to come across mythril weapons besides patronizing Nono? I'm trying to get all the equipment necessary for learning all the abilities, and these appear to comprise the only part of the plan that's going to give me much trouble.

I've only ever picked up the staff for White Combo, won it after some random battle pretty early into the game, but I haven't ever seen any others myself.

I've got Mythril Knife, Mythril Bow and Mythril Lance so far..

There isn't a reliable way to get them.

You just need to keep going to Nono and/or engaging those wandering Soldiers on the world map.

I figured. Well, then, is there any way to get Nono to replenish his inventory without linking games?

Actually, it's a good deal more reliable than you think.

It has to do with fighting the randomly wandering clans. Beat each of the different clans often enough, and you'll get mythril equipment.

That's how it's worked for me.
