This page is an overview of how the damage amount of a damage instance is calculated. It covers armor and attack types, damage types, armor rating, ethereal units, minimum damage and abilities, that directly modify damage.
Damage instances are all instances that deal damage. Each damage istance consists of the damage source, the damage target and the damage amount. This page covers how the real damage is calculated from the damage amount of the damage instance. Damage Instances are usually created by:

Every damage instance (created by an attack instance) has exact one attack type and every unit has exact one armor type. The combination of the attack type of the damage instance and the armor type of the damaged unit evaluates to a damage modificator.
In warcraft there are a lot damage types, but only very few people actually know them. Damage types affect, if a unit is damaged by a damage instance and if the damage is reduced by armor and some abilities. The most important damage types are:

All attacks in warcraft 3 have damage type normal. Even attacks with attack type magic have damage type normal. Normal (damage type) damage is reduced by armor rating. This damage type is also referred to as physical damage.
Enhanced physical damage is similar to normal damage, but it is not reduced by armor.
Most spells in warcraft 3 have damage type magic. Magic damage (damage type) is not reduced by armor rating. Spell immune units take no damage from magic damage (damage type).
Universal damage is not reduced by armor rating and also affects spell immune units. Most damaging ultimates have damage type universal.
