Capes are acquired by joining a guild that has one, or buying one from the Guild Emblemer if you are a guild leader, which costs 2 . Capes bear the symbol of your guild, and you are required to have one to buy a guild hall. Only guild leaders can change the cape of a guild, but every member has the ability to preview a cape design on the Guild Emblemer pane.
The guild cape is worn on all of your characters on your account. Much like your character's headgear, you may set it to be visible only in towns, only in combat areas, both,or not at all (via the Inventory screen). However, you are required to wear it in PvP combat to represent your guild. The cape's color scheme alters in PvP depending on the team color - blue, red or yellow - but the emblem remains unchanged. If you join PvP battle without being in a guild, you will temporarily get a blank cape without an emblem for every battle. This kind of cape doesn't appear in your inventory and disappears after the battle ends, or when you leave the battle.

 Other colors of trim
Tolkano offers guilds the ability to change their trim to some other colors in exchange for 2500, 7500 or 15000 Tournament Reward Points. These cape trims do not expire and will overwrite any trim that the guild already has. If the guild wins a Monthly Automated Tournament, the gold trim will overwrite any trim that the guild has.
