Is artifact armor infinitely recoverable?

[Omedon]

The level 50, 70, 80 and 90 ones can be rebought either from the calamity salvager or the npc that originally gives them. The level 60 one can only be rebought with centurio seals

Well that's both a relief and kinda random on the part of the level 60 ones, thanks for clearing that up! I haven't gone deep into hunts so I don't know if that's more or less a pain in the ass, but at least they are recoverable, thanks!
