- Gunsmith Engrams also drop from patrol chests and (I think) the resource nodes So, they're pretty easy to get while doing Distortions - I think the only other way to get Legendary Marks outside of Triumphs is through the Seasonal Hub challenges - Renegades Rep, make sure you're stacking as many challenges as you can, for as much material as you can turn in

1. Vanguard Reputation: The fastest way that I have found is playing Vanguard Alerts. Both Fireteam Vanguard Alerts and Arena Vanguard Alerts. 2. Legendary Marks: These will drop in abundance from completing active orders, daily objectives, and weekly objectives. These can all be done at the same time as you're running Vanguard Alerts. 3. Gunsmith Engrams: These are easy. Dismantling weapons help you level up with the Gunsmith. You will end up with a ton of weapons to break down as you're running your Vanguard Alerts and really from any game play. 4. Renegades Faction Rep: This will be a bit of a grind. You have to align yourself with each faction, and you can only be aligned with one at a time of corse. Then you have to run Priority Contracts for that faction until you level up to 5. I believe donating to the faction helps as well... Hope this helps and good luck...
