Would it possible to add the paladin smite so that when used it uses up a spell slot, either added in as a scaleable spell or some such 

thanks 

You just click one of the unfilled tick boxes in whatever level spell you want to smite with.

Yes I understand how to do it, but I was asking would it be possible for the beyond team to make it part of paladin sheet, especially when used in connection with digital table top gaming 

I think chances of it happening any time soon are exceedingly low, but you could probably homebrew yourself a spell that would function like a smite, including being levelable.

In fairness I’ve done that, annoyingly though you have to give up another spell known to use it, not the end of the world 😀

You could make a feat or item that will grant the spell. Used to be that you could overprepare spells, too, but they did away with that workaround. :/

That’s a good idea didn’t think of that, thanks 

If you add it to the subclasses rather than the core class it considers it to be always prepared like oath spells. This means that your homebrew spell won't appear until you select a subclass at level 3 but does mean you don't have to give up a preparation slot. This is the way that I have done it.
