 ### Added
 - Spicework has been implemented. You can now craft food and drugs in your hearth, once you build a spicebench.
+  A character can only have one food condition and one drink condition at a time. If a second food or drink condition
+  is gained, the old one is lost. There is no limit to the number of drug conditions a character can have at once.
 - New hearth amenities: spicebench level 1, spicebench level 2
 - New items: bluster powder, mudtub mash, midoras spice, midoras mudtub mash
