More on Guild Banners...

The "Banner Material Kit" and "Banner Dye Kit" are the items that are used to create a banner and place it in the world.

When you open the guild window and go to the "Banners" Tab, you should see a list box with a single entry that says "Standard of Honor". Just beneath that list box, you'll see a checkox that says "Show All", select it.

This will populate the list box with a bunch of banners that are going to be greyed out (which means you don't have the components to create them). Just beneath the checkbox you checked is the description window, which will give you a brief description of the banner's effect, as well as the items needed to create that banner, which you may then purchase those items from the two guild banner vendors in Plane of Knowledge.

The "Banner Exchange Insignia" are used to edit the settings (looks) if your banner. The more you change the looks of your banner, the more it's going to cost you by requiring a higher tier of exchange insignia.

Placing a banner requires 12 guildmates to be in the same zone within 150 distance units from the player planting the banner. If they're too far away, they will not be able to place the banner.
