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.

У персонажа нет стата Holy Resistance, соответственно и все баффы на +all resistance его не увеличивают.
Но все эффекты поглощения и понижения урона на данные заклинания работают.
