In the case of hirelings, it can be helpful to boost their health in case they're near death, but it won't be something you use very often. The healing effect is also relatively small, nothing that will be making healing potions obsolete. Holy Bolt allows the Paladin to damage Undead foes from a distance directly, but it also lets him heal hirelings or other players.

Energy should be increased through armor only and not by stat points.Strength and Dexterity should be enough for you to equip any armor you'd like. Every other point that doesn't go to the first two should go to Vitality.Dexterity is the second most important stat to a Paladin, simply because Paladins have no form of Combat Masteries that will give them large bonuses to their Attack Rating, making it difficult to hit enemies later on in the game.The Paladin will want to make sure he has plenty of Strength, enabling him to wield any armor he comes across in the game.Though they don't possess the raw power of other melee-oriented classes, the Paladins can reduce their enemies' defensive capacity, directly damaging them with their auras.

In addition to their auras, Paladins are equipped with combat skills that give them an edge on the offensive end. The Paladin comes with many offensive and defensive auras, all of which will be shared with allied characters and minions when they're within range.
