Also new is our clay farm. On level 5 planets, clay drops 8,4% Raw Waxy Earthyam, the same amount of level 6 planets. Source
While it’s easier to farm Raw Waxy Earthyam with mud, there is hardly a reason if you need clay to farm it on anything below a level 5 planet. You need only 2800 damage to one hit clay on level 5 planets.
The farm contains 3x3 plots of pure clay, 1728 blocks. Nothing will stop your shovel from plowing through!
The farm has a door. In the unlikely case that the regeneration bomb kicks you out you can easily get back in.
The farm can be reached from the EFC hub.
