The Guild Banner Designer is a replica of the Guild Emblemer: you can design your cape, change patterns, colors and emblem with the same options like the one in Guild Wars. Also, you can add a cape trim and export your creation.
The other 7 trim colors (blue, green, orange, pink, purple, red and obsidian) can now be picked, have fun!
Whenever you use a skill with a different attribute than the last skill you used, you gain a 5% stacking damage bonus (maximum 30%). This bonus resets if you use a skill with the same attribute as the last skill you used.
