The High Aldwin
Well, ask the DM. It is how I do it, other DMs I know do it, and even @Stormonu suggested the same thing because, frankly IMO, it is the way it should be.Wrathful Smite is only on the Paladin list. If I could do that I would be all over it.

It certainly isn't "too strong" or anything, even granting half-caster access to cantrips. Having to use your fighting style for it is overkill.
