There's a lot who claim xur to not be rng but I think he is; however, if he were to sell red death tomorrow I might think different. A guarantee of health when hard mode offers no way to regen? There's something there. This is only furthered if while selling red death he sells one or more of the following: Third man Skull fort Apotheosis veil To a lesser degree Stand asides Don't tug me I don't know of any other warlock tertiary heal oriented gear. That would just be too coincidental for me to go, yea that's random.
