Ah, I see it now. It is the Aura of Hate that is giving the extra damage. It's a level 7 feature of the Oathbreaker Paladin, and gives the Paladin a bonus to melee weapon damage equal to the Paladin's Charisma modifier. Str of +4 and Cha of +4 gives you a total of +8 to damage.
Be sure to give the full feature a read, as it is an Aura that affects more than just the Paladin.
