Other things to remember: You can divine smite once per attack, but can only eldritch smite once per turn. Also divine smite can use any spell slot, but eldritch smite requires using warlock slots. Also, paladin’s extra attack and warlock’s thirsting blade do not stack.
Can you do divine smite twice?
TL;DR: other than “1 spell slot per attack” and “max 5d8 damage or 6d8 versus undead/fiends per use of divine smite” there are no limits.
Can you cast divine smite twice?
Why does Eldritch Smite only work on Warlocks?
The OP is referring to the Eldritch Smite warlock invocation from Xanathar’s, which is similar to paladin smite but can only be powered by warlock spell slots. As to the why, my assumption is that they realized letting paladins use any spell slot to smite was probably a bad idea, and had no desire to give the ability to yet another class.
Can you use any spell slot for Divine Smite?
You can use any spell slot to Divine Smite, regardless of where it comes from. As per the multiclassing rules, all of the other spellcasting classes get their spell slots lumped together for the purposes of casting spells (see the Multiclass Spellcaster table on PHB page 165).
Can you cast divine Smite as a Paladin?
You would be able to use the warlock pact slots to cast Sorc spells but as Paladin Levels do not contribute to your pact slots only spell slots they would not be usable for Divine Smite. Most other spell casting refers to the use of Spell Slots in general and not a class specific spell slot.
Why does Divine Smite not have a restiction?
Divine Smite (paladin) does not have the restiction because there’s no such think as ‘paladin slots’ if you multiclass into another class with normal spellcasting – a sorcadin doesn’t have separate paladin and sorcerer slots – so resticting the ability to paladin slots isn’t really possible.
