So, for those not aware, you have to collect 'Lost Treasure' by killing enemies throughout the system. When looking at the bounty on D2checklist, it shows that you need 350 of these lost treasures (the bounty itself in game just shows a %). So far, not a great problem. Get 350 kills and all done... Well, that's where the problem comes in. The actual drop from killing enemies is RNG as to whether you get a lost treasure per kill. From a very quick calculation after visiting the thrall pit in the Whisper mission, and checking the progress on a masterworked weapon, I estimate I was averaging 1 treasure every 10 kills. That leaves it as approx. 3,500 kills just to complete one bounty, which seems quite excessive (especially during an IB week when people will want to be spending time in the crucible, not killing thousands of PvE enemies).
okay solution to this.. on console: go to settings -> date and time -> set manually - set clock to somewhere in the past -> return to game -> load into patrol area on mars -> see if you are alone in the roster - if alone start escalation protocol - kill thralls / perfect point to do banshee 44 bounties.. -shadow rift apears , change to other patrol area - repeat - - finish.. this is how you fast grind such "kill 2 billion enemies" bounties without disturbing or wrecking other peoples experience since you will be the only one in this instance anyway.. have fun.
