Eticore's Discreet Diplomat

Choose a humanoid that you can see throughout the casting of the spell. For the spells duration you have advantage on Intelligence(History) checks made to recall lore about that creatures culture. In addition, the spell sends a mental warning if ever you might accidentally partake in a course of action that would be seen as insulting or offensive in that creatures culture. This spell only grants insight into the culture as a whole and does not account for personal differences. The spell also does not administer a warning when you are about to partake in an universally offensive act such as committing a crime.
