Case the Joint #Microfeats
Case the Joint. You can take one hour to make a Knowledge (local) check to analyze a structure or building. The DC is equal to making a Knowledge check for the highest-level creature that built it or currently uses it regularly. You can information about one of its strengths or weaknesses if you succeed, and one additional strength of weakness for every 5 you make the check.
#Microfeats are experimental feats we have in playtesting or development (and may well change before they ever get used in a product – or may get cut entirely).
