Destiny 2 Warlock BuildInfinite coldsnap prismatic warlock

Pick any super, jump, and class abilities and use at least one void weapon and one strand weapon.

This build is all about taking the osmiomancy gloves build to a whole other level.

You start by consuming your grenade for a turret, and then throwing the other grenade into a battlefield. Because of Facet of Balance, rapid kills with dark damage gives grenade energy, so both your turret and your grenade will be refunding your grenade charge.

You then want to be using a strand weapon and a void weapon, and take advantage of the Facet of Bravery fragment. Every time you get a kill with your stasis grenades, you get devour (which just gives you back more grenade energy), and you also give your void weapons volatile rounds. These volatile rounds can be another good source of activating devour, and getting you your grenade back. This also gives you melee energy because of Facet of Balance.

If you are not able to get a grenade charge back with your void weapon and devour alone, you can get a melee kill to give your strand weapon unraveling rounds. Because of Facet of Balance again, your strand weapon kills will quickly give you your grenade back. If it doesn't and you still have devour (which you should have because of how much it activates), your kills will also give you your grenade back.

I don't exactly know the numbers, but I feel like this should be able to get you back your grenade really fast.

You can use your mods to get even more grenade back, and you want to be able to get your melee back.

This build should also be able to get you transcendant fast, because it balances the dark damage with the light damage. You can also use your mods to give you a lot of super energy, since this build lacks a fast super.
