This formula has a potency of “five skulls” (the maximum), and will be strong enough to keep the questline moving. It involves green liquid on the left, orange in the middle and blue on the right. Just take a look up at the barrel of liquid at the control panel and see what color it is: move the device to dump the liquid in the right container, then repeat the process twice for the other colors. The colors are chosen automatically.
And that’s it! Once you press the left-most button the brew will be complete.
