Stats used:
Usually WIS if it involves relying on book learning. BLE may be checked if it involves an economic or spiritual practice. SHA may be used if it involves something related to sociological and cultural empathy matters. 
The more obscure the culture, or the less the history or traditions have been documented, the more difficult a Lore check will be.
Resist: This usually doesn’t have a resist skill. Either the user knows it or doesn’t.
Success: The user successfully recalls and can apply knowledge related to culture and history.  
The user cannot recall cultural or historical details, or gets them wrong. A botch might cause a bad cultural gaffe and cause offense or embarrassment.
