Heya Buddies, Revenge of the Cartels (2) Event came out recently and just like many others I Immediately farmed the OPQ System Legendary as soon as I can. The OPQ System is considered to be one of the best guns in the game so I just had to make sure to farm it right away and create a build. This build we are taking advantage of the Mind Sweeper Class Mod skills to deal some serious damage and to give us the ability to infinitely gain ammo without investing heavily into the green tree. The Mind Sweeper Class Mod also allows us to spawn micro grenades and sometimes this procs over and over to basically give us infinite amount of damage when lucky. We are using Moze because of her Short Fuse ability & tons of other Splash Damage based abilities to optimize our DPS as much as possible.

Lets first talk about how I effectively gain infinite ammo without going to the cap stone with the green tree. Mind Sweeper allows us to gain an extra point into redistribution which requires us to just go to the tier 2 on the green tree to give us ammo regen up to 10% with every crit (5% for each point). Since we are using the mind sweeper dealing crits is heavily suggested to proc its effect so naturally you will in turn be gaining 10 % Ammo regen as often as possible but this isn’t where we gain most of our ammo regen. Where we gain most of our ammo regen is just with 3 points into means of destruction, since the OPQ system does a Shock nova sometimes on hit it can proc the means of destruction skill more times then most kinetic weapons. Combine that with short fuse & micro grenades you are able to gain almost infinite ammo back since you would be dealing splash damage randomly all the time. Sure there are times where you might get unlucky and still have the reload but the chances are low. Here is a great video that showcases this on jack’s test dummy. Of course that video the OPQ they are using has a bigger magazine size then mine but the idea is still the same except we have the added benefit of the micro grenades to help boost our chances.
Other Gear we Use: On top of the weapon and class mod we also use a Its Piss grenade with On thrown bonus damage anointment, a Pearl of Ineffable Knowledge for bonus damage and finally a Super Soldier Shield w/ ASE Bonus Fire damage; despite recent nerfs this shield helps immensely for ammo regen and helping to increase our DPS without multi stacking Phalanx Doctrine.
Its a ton of fun and I would love for you guys to try it as well. Look above for this Moze build Save File. Alrighty that’s all I have for today, Have a great day everyone
