As part of its final ever content drop, a new secret Exotic mission has been added to Destiny 2. The reward is Cull’s Shadow–a fusion rifle with the intrinsic trait of Soulburn. Soulburn means that final blows or rapid hits with the weapon’s frontal blades heal you and provide Soulfire Charges, which cause rounds fired by Cull’s Shadow to inflict potent corruption. The frontal blades deal increased damage to targets afflicted by that corruption.
