Choose one. (1) Select an enemy follower on the field and deal it 2 damage. (2) Discard a Royal Paladin card: Select an enemy follower on the field. Deal it 3 damage and give your leader +2.
QWhen playing this spell, if I can't select an enemy follower on the field, can I still choose option 2 to discard an Royal Paladin card and give my leader +2 defense?
ANo. If you can't select an enemy follower, you can't play this spell.
