As a hero, he cannot be converted and can regenerate health (since The Conquerors). He has the appearance of a Paladin with similar stats but has higher melee armor and more hit points except if the player is using the Franks (which they are in the Joan of Arc campaign), in which case a regular Paladin has two more hit points. Also Guy Josselyne moves faster but attacks slower than Paladins. Technologies that benefit cavalry also benefit Josselyne, but he is not affected by civilization bonuses.
