Identify when group members could change their Ominous Chromatic Essence trinket attunement in order to fill a missing buff.
This aura checks whether any of the 5 buffs are missing, and if so checks whether any group members are using the same stat for their attunement. If there is a dupe the aura will appear and show which buff is missing, and list the players who could change in order to fill it.
There's also an option to always show all group members who have a OCE equipped, but this defaults to off.
