how about instead of keys beeing bounty reward, make a parts already bountie reward?
un-vault will took 2 months during which there could be potentially second tree of bounties were rewards could rotate just as normal bounties do
this way there wont be a double "dice check" first on relict and then on relict itself reward and fe. rare relict rewards would be the rarest bountie reward
and god dammit are there any plans to make bounties a bit less dull? plague star event make them something that most people would prefer to avoid at all cost
