This question concerns a multi-classed Bard (College of Whispers)/Paladin who has acquired the spell Tenser's Transformation as a magical secret.
Could such a bard use their Psychic Blades feature to add damage to their attacks? What about using the Divine Smite to empower their attacks?
I understand you can't cast spells while under the effect of Tenser's Transformation - but can you either of the above options to deal more damage?
