How do you get all the Mythril weapons which teach your people combos...

When you trade items, units, or link up with friends, (after you save Nono, Monblanc's brother) Nono, when you enter a shop, will say I have some more trade items.

When you go to "Trade Items," Occaisionally, you will see the catagory "Metal" it will cost 5000 gil to buy, but it will give you Mythril weapons.

Sometimes, they will be weapons you have already, but sometimes you will get new weapons.

You can also, BEFORE you go into the shop, save your game, then enter the shop, and when Nono says he has some trade items, if you don't see any "Metal" then you can turn your game off and there will be a different set of Trade Items.

Hi
To get all mythril weapons, wander around beating other clans. You can get them for winning. Alternatively wait untill near the end of the game and you can buy them in Cyril. They cost a lot of gil though.

Kay, I have a question to ask you first.... Where did you get a Mythril Bow?!?!?
I only have a Mythril Reaper, a Mythril mace, and a Mythril Gun..... I got these from beating up the little red dudes on the map and saving my turf......

The way to obtain mithril weapons earliest is to simply skip ANY missions and just grind beating the other clans that appear and roam around the map. The item you win is random, but eventually you're bound to gain a few mythril weapons. I have around 5 or 6 different ones including both types of bows. Also, if you don't do any of the other missions you don't have to worry about the item stock availible going up. Since you can win any item available to you after beating a clan, and mythril weapons are always available from the start of the game, it's wise to just beat up other clans if you don't want to dish out the large ammounts of gil.

You kill people.

Easy tips to get mythril items is when a red turf is on the map or other clans and if it is your first time fighting that clan then fight them, after that you'll get a mythril weapon as simply as that.
