Something that isnt noticed in the wiki, but is very interesting for late game gluttoning: charred something
Yes im serious
Charred something has not only random gluttony values but also random debuff timer debuff penalty and debuff chance. I havent experiemented a lot with it, so I dont know the ranges, but I can show you one of my charred somethings:
some irrelevant random glut values
full and fed for 0:10
reduces meat with 41% (0% chance)
restores slugs with 20% (10% chance)
so the 0% chance to give food penalty, basically gives some free glut values + chance at restoration (depending on what meat you used)
