The Holy Cannon of the Traveler. Taken from the Vanguard tombs: "With the Traveler's blessing, thou shalt smite they enemies from on high." When a guardian activated the Holy Cannon of the Traveler, his equiped ammunition becomes tracker rounds. Any target struck with these rounds will recieve no damage out right. When the one who activated the Holy Cannon of the Traveler deactivates all targets marked are hit with/struck down by a gravitational pulse lazer emitted from the Traveler it's self. The Activatee can deactivate the marking phase at any time with no max duration. However if the Activatee or the mark targets die before the deactivation the marked targets are no longer marked. Furthermore the Activatee is required to sing aloud praises to the Traveler. (Player will sing praises over voip without restriction to his fireteam) To ensure worthiness to the Traveler as he is marking said targets.
