This ??? is near some nearby goblins who will link at will with the NMs; it is recommended to clear the area or pull the Goblins away from their initial spawn point.
The Goblins will begin unclaimed. If left unclaimed for over 1 minute, they will despawn resulting in an automatic failure.
Others assisting with the fight may also check the ??? after the win for an exp/limit reward regardless of whether they have the mission active. However. if they do not have the mission active, they will not receive Allied Notes or credit for the victory.
After defeating both Goblins if you do not check the ??? after 5 minutes. It will say 'Nothing out of the ordinary.' resulting in an automatic fail.
