Destiny 2 | Solo Grandmaster The Disgraced on Prismatic Warlock | Episode: Echoes 

Graviton really excels in clearing large amounts of rank-and-file ads, but falls behind in environments where you have to deal with large amounts of majors/champions. Solo GM is such an environment and that's why I use it here. And it's where Outbreak starts to shine: its ramping single target damage helps to cut down champions/minibosses quickly and helps with boss damage as well. This build has plenty of ad clearing stuff already (shatter damage from turrets, transcendence grenades, voltshot sidearm), so there's no need to slot in an ad-clear centered exotic weapon

The boss of this strike is really annoying to damage, so i chose a damaging super with a relatively quick cooldown to cast it a lot during the final boss room. Song of Flame is really good for damage + survival panic button purposes but its cooldown is longer and i didn't feel a need for additional survivability in this particular GM

Thank you for pointing out, updated the DIM link as well
