Cross class bartering

As you progress through Middle Earth you can earn different kinds of currencies. Some go into your Barter Wallet (Marks, Medallions and Seals), and some go into your inventory and can be shared with your other characters (Medallions of ***). If you have the Upgraded Barter Wallet, all Medallions of *** will go in there as well and can be shared with all your characters.

There are various Landscape tokens as well that pertain to specific regions. Some of these tokens can be used to barter for armour as well, regardless of class. Just keep in mind that the item will be bound to the character you make the purchase on, and that you will need Wardrobe space to use the item cosmetically if your character is of a different class than the armour you purchased.

At first you probably only use these currencies to gear up your character, but once you are satisfied with that, you may consider using some of these currencies to purchase armour from another class to use cosmetically. I recently realized that not everyone is aware of the different options that are available to obtain armour that is intended for a class other than the one we play, so I’ve tried to compile a summary of all cross class barter options.

Obviously, you would only buy armour from another class for cosmetic purposes, as you cannot use armour that you do not meet the class requirements for.
Don’t forget you need the Wardrobe to cosmetically equip armour from another class!

Reminder: the Cosmetics vendor at the Skirmish Camp also sells cosmetic versions from many sets.
