FOUR Lightbringer skills?

Like the Sunspear Title Track, there are nine ranks in the Lightbringer Title Track, but the title has an additional mechanic. When you display your Lightbringer title (by selecting it in your character's Hero panel) each rank of Lightbringer gives you +5% damage against demons and +1 damage reduction against demons. Four "No Attribute" skills available in Vabbi also become more powerful as you gain Lightbringer ranks. For anyone fighting wave after wave of minions enslaved by Abaddon, gaining Lightbringer ranks can make crusading against the forces of darkness a little easier. Is this a typo or is it a hint that they're adding more Lightbringer skills in the future?
