@JeremyECrawford @Dan_Dillon_1 does resistance stack? If you have resistance to fire as a tiefling would something that gave fire resistance add to that ?

No, resistance only applies once no matter how many times you gain it for the same damage type.

To read more about damage types, resistance, and vulnerability, see Player's Handbook page 196-197. #dnd #WotCStaff https://t.co/znFT73RUSe
