Nice, I can make twice-as-expensive bone clay for my prerequisite to craft bone clay. At this point, pit clay's only purpose in life is to allow someone to skip the excruciating torture of grinding lye. Even after the most recently patch buffing the production, I've still been at this for 20-some hours now just burning more bones than a crematorium, and boiling more lye than a shady chemist.
Reduce the lye cost from .2 to .1, or even to .05 to reduce the insanity of awful bone grind. This is a travesty disguised as a blessing.
