Landfall gives you a super within a super.... it's a great exotic. If we are looking at warlock exotics that actually need buffs: Apothyosis Veil (too situational) Purifier Robes (make the blinding effect on radiance activation, fireborn should not be a requirement.) Alchemist's Raiment (just all around worthless) The Stag (too situational) Skull of Dire ahamkara (50% damage resistance is a bit low considering roaming supers get that, although I wouldn't put this as a top priority.)
