How to earn the Best of Both Worlds achievement / trophy
New achievement / trophy today with the GOLDENLOOP update.
Karl's Bay Afternoon
Head to the Forever Young building in Karl's Bay afternoon and use the Trinket Machine. Collect residuum (or kill yourself and absorb your personal stash - see video) and use the machine.
The machine now makes the new 2-in-1 trinket and legendary trinkets.
Pretty easy achievement.
