SDKA

With a glitched room and the current boost, i managed to get SDKA in 2 days, i did it with 2 metals which were far from the most efficient & a glitched room, arsenic and chromium, chromium being the first drop. scoogle's method requires alt accounts which can be bothersome to keep logged in for longer periods of time, however, if you combine all 4 factors, testthisaccount123's recent discovery, the drop boost, a glitched room & perfect metal rolls forget a month or even a few days, i wouldn't be surprised if you could pop out SDKA in a day with prefarmed metals.

I got super luck with thew metals Too, the first was rhodium next day was Arcenic
