Reverie dawn armour currently does not drop with the riven's curse mod on warlock and titan, and hasn't been for a while (since around season of the plunder, when the gift of the thunder gods was introduced). Since the offering to the oracle bug has been put in the known issues (makes transcendent blessings unobtainable) and since its a dreaming city season i would love to see bungie acknowledge riven's curse being unobtainable aswell

Hope they finally fix this after more than a year. I'd love the get Riven's Curse on my Warlock to deal more damage in the Dreaming City, especially with this season revolving around it!
