Essences for the 4 missing runes: life, spirituality, physicality, and death. Items, icons, and runes are included, and you can make them with furnaces just like the original essences. Plug-and-play: all you have to do is add one line to your init.lua. No credit required!

Note: the furnace/beacon runes were kind of a rush job, so the normal map is cruddy.
