Select a team in the Free PvP UI; the chosen team is displayed overhead. Using a cape renders the helmet invisible.
Team capes are used by mounting them in the event slot; a mounted cape enables free showdown with players wearing a different cape.
The Free PvP icon over a character's head denotes willingness to engage; other characters displaying the icon can attack them at any time.
