http://vanilla-wow.wikia.com/wiki/Magic ... oW%29#HolyThe Holy school is usually related to abilities which heal and aid living beings. There are also a few spells that do Holy damage: Smite and Exorcism, for example. Contrary to popular belief, Holy Magic does not deal additional damage to undead or demons unless specifically mentioned in the tooltip (such as with Exorcism).
Priests and Paladins are the primary users of the Holy school, including all their healing and resurrection abilities.
It is not possible to resist Holy magic, giving it a slight advantage over other schools, but it does have a
basic miss chance like all spells, offset by
Hit rating.
Items and Buffs which give a bonus to all resistances, such as Mage Armor,
do not include Holy resistance, but
percentage-based damage-reduction abilities such as a Warrior's Defensive Stance successfully reduce damage from Holy spells. Also, the [Holy Protection Potion], [Greater Holy Protection Potion], and [Major Holy Protection Potion] items will also absorb limited amounts of Holy damage.
