:sload soap:
Sload soap is a waxy substance made from the immature non-sentient forms of the sload.
If you really want to wash yourself with the corpses of baby slugmen, I suppose you can. I just can't imagine it being particularly hygienic.
But the name itself implies the existence of soap, even if it's not provided in game. If medieval europe had been a true trash pile with absolutely no concern for hygiene, how comes knwoledge of sopa and thngs like public bathes, lavoirs and the like wouldn't have been widespread.
Sur it wasn't exactly squishy clean, but the medieval period wasn't a pile of inbred brutes caving eash other's skulls and [censored] their sisters amongst piles of their refuses and dejections.
