Naw man it's not random. At least that's what it looks like. People begged for last word he sold it, people begged for plan c he's selling it next week will probably be gjallahorn since there's a f ton of people asking for it now. If it was purely random there would be a lot more than two weapons that have been sold twice. Although I don't really know what's goin on with the armor 5 weeks of voidfang suggest the armor side of it could be random, or they just hate warlock users
