This seems very expensive so I’ll help yall.

Metal, element and obsidian are all easily gathered by an anky. Just make sure to have an argy with a high weight to carry the anky and/or the materials.

Cementing paste can be gathered in the beaver dams. You get at least 100 cementing paste in every dam.

Finally, crystal can be gathered with a metal pickaxe, or a mining drill if you have one.

I hope this helped. Yours truly, the moeder flag guy :)
