I was wondering if the bonus you get from smites stack together if they are from two different sources.
Like for example when a paladin's mount form the divine bond gains the simple celestial template and gains the ability to smite once a day.
Special Attacks: The creature may smite evil 1/day as a swift action (it adds its Cha bonus to attack rolls, and a damage bonus equal to its HD against evil foes; smite persists until the target is dead or the celestial creature rests).
And when the paladin gain's the Aura of justice ability
At 11th level, a paladin can expend two uses of her smite evil ability to grant the ability to smite evil to all allies within 10 feet, using her bonuses. Allies must use this smite evil ability by the start of the paladin's next turn and the bonuses last for 1 minute. Using this ability is a free action. Evil creatures gain no benefit from this ability.
A paladin and her mount gain both abilities at the 11th level. If the paladin uses her aura of justice ability and the mount is within range and gets it and uses both the smite it got from the paladin as well as it's own. Would the bonuses it gets to it's attack rolls, AC, and damage from both of the smites stack together.
I did a little searching on the matter and from what I read at least the bonuses to damage would stack because both are considered "untyped bonuses" But I still need further clarification on this. Any help would be greatly appreciated.
only the damage has a chance of stacking. And even then it probably doesn't since the source of both is smite evil
