Solo Legendary Campaign "The Witness" Final Boss - Warlock Build/Strategy (SPOILERS) 

Solo Witness | Solo Final Shape Legendary | Solo Witness Warlock | Warlock Prismatic Build
Just a clear of the final boss fight of the Final Shape Campaign with the Osmiomancy warlock build that I've been loving since the expansion released. MASSIVE spoiler warning for this one.
Hope you've all been enjoying the Final Shape!
