When I applied this mod with many of its optional dependencies I looked pretty good as it provided many essences which I thought coul be useful.I was even surprised to see more than even 9 essences of uranium itself and immediately got to work to craft and farm them but all of yhis was a moment of joy only for a second for which I realized that only 2 of them were useful rest were totally useless to be farmed even. It was a total waste of time to craft,farm and harvest them for no good. Same with some default essences like earth essence and dye essence which are just worthless to be even crafted.
So please fix this by adding usages to the essences and make them worth to be crafted and used by players.But still I have to say that you have put great effort for adding those essences and their seeds. But still please add the cast iron essence and seeds
