*Edited for new way to farm during Season of Arrivals
Let’s take a look at the PVP God Roll for the Legendary Solar shotgun Seventh Seraph CQC-12. This rapid-fire frame hits pretty hard for this kind of frame. I have seen a good amount of CQC-12 in the crucible, but of course, it will not overtake the Mindbender’s Ambition. It rolls with similar perks as Mindbender’s so it’s worth grinding for. This roll, I am looking to max the range as far as it can go, readiness, and takedown supers. I am not going to lie, this was difficult to pick out because it has a lot of variations that you won’t be disappointed with. Let’s get to the roll.

Barrel
Rifled Barrel. This is becoming the best barrel choice for shotgun because it increases range with the increasing projectile spread. Rifled Barrel does decrease handling but it will not matter once we get into the perk we are choosing for this roll.
Magazine
Accurized Rounds. The top choice to increase range with no downfall to other stats.
Perk 1
Quickdraw. While rifled barrel decreases handling, quickdraw counters that reduction making the weapon snappy. This was a hard choice since this column can roll with Slideshot. I would not be mad if I get Slideshot but with handling taking a hit you would feel the difference.
Perk 2
Vorpal Weapon. Increased damage against bosses, vehicles, and Guardians with their Supers active. We want to take down those supers charging towards us.
Mod and Masterwork
Range masterwork and Icarus Grip mod. We need to push as much range and be as accurate in all situations especially in the air. Not sure about you but I jump every time a Super is heading towards me just in case it goes underneath my feet. It never does. These two work well with each other.
The best way to grind for this weapon is to speed run the Legendary Lost Sectors. Fallout Plays(follow him) has a video about bit farming the IO Legendary Lost Sector Sanctum of Bones. He completes the activity in around 30 seconds. That is fast compared to other Lost Sectors. Instead of bit farming, this also gives you a seventh seraph weapon if you open the silver chest. The only thing you would need is an encrypted warmind bit. One issue is the chest gives you an item from a large loot pool ranging from weapons and armor from the Seventh Seraph brand(11 items). Luckily the speedrun takes you less than 1 minute to complete and start all over. The weapon also drops in other activities but that is a low chance but a higher chance when you run with a clanmate. Run the Legendary Lost Sector.
Now you know the roll for Seventh Seraph CQC-12 for PVP and where to grind for it. This roll will help you go against players in all situations. If a Titan is charging at you ready to shoulder charge, quickdraw has you covered to be in a position where you have a chance to react. The same goes for enemies who have their Supers active. Vorpal can take down players where Mindbender’s Ambition may not. Get to grinding Guardian.
*Edit: Season of Arrivals has this shotgun in the focused Worthy Umbral Engram.
