@JeremyECrawford Still unsure what the mac allowed damage of Divine Smite as a whole is. 5d8 using a 4th level slot? or 7d8 using a 6th?

Divine Smite can deal a maximum of 5d8 radiant damage, or 6d8 if the target is an undead or a fiend. #DnD https://t.co/1wqtPrmdB0

@Sunglare @AiratomeBut what if they multi class Warlock and use a 5th level slot?
Multiclassing doesn't change how Divine Smite functions.
