Thanks to the recent nerfs to the Well of Radiance in Destiny 2, Warlocks can finally try out some other build options in the game, and Prismatic has a lot to offer in that regard.
Prismatic Warlocks Are Officially The BEST Damage Class | Destiny 2 The Final Form
Here are some of the best Prismatic Warlock builds to use in Destiny 2. The base versions of these builds do not require the Solipsism Exotic class item, but they can be enhanced with certain combinations listed in each build's description.
Osmiomancy Gloves without Coldsnap Grenades may seem counterintuitive, but the ability to regenerate grenade energy on hit applies to every grenade in the game, even outside of Prismatic. This allows you to flood the battlefield with Void grenades, which also ties in nicely with the Echoes seasonal artifact.
The main element of this build is the Feed the Void Aspect, combined with Facet of Dominance and Facet of Bravery. With each ability kill you gain Devour, which you can level up with more kills and regenerate extra grenade energy. The Fragments allow your Vortex Grenades to weaken targets and grant Volatile Rounds for your Void weapons.
