Armor Types

Unarmored (most spellcasters)
Unarmored takes extra damage from Piercing, and Siege attacks. Some unarmored units such as Huntress, Gargoyle, Hippogryph, and Druid of the Talon in Storm Crow form have armor for balance reasons. Most unarmored units do not have armor.

Light (most flying units)
Light armor takes extra damage from Piercing and Magic attacks.

Medium (most ranged attackers and workers)
Medium armor takes extra damage from Normal attacks, reduces damage from Piercing, Magic, and Siege attacks.

Heavy (most low and high tech melee units)
Heavy armor takes extra damage from Magic attacks.

Hero
Heroes take reduced damage from Piercing, Magic, Spell, and Siege attacks.

Fortified (buildings)
Fortified armor greatly reduces Piercing, Magic, Hero, and Normal attacks, but takes extra damage from Siege attacks.

Note
Ethereal units can only be damaged by units that have the attack type "Magic" such as spellcasters. Magic-immune units can only be damaged by units that have physical attack types.

Damage and Armor Class System
Every unit in the game has an armor type and attack type (like StarCraft).

Each attack type is better or worse versus other armor types. For example, a Grunt has a Normal attack, which does 150% damage versus "Medium" armor units like the Archer, Rifleman, Troll Headhunter, and Crypt Fiend. The Archer has a Pierce attack, which does 100% extra damage versus "Light" armor units like the Gryphon Rider.

This system is in place to encourage unit counters and unit mixing in combat. If the opposing player builds ranged attackers, then the natural counter would be to build melee units, which have an attack bonus versus them. However, since ranged attackers have a high damage, you would benefit by building a mixed group of melee and ranged attackers since your ranged attackers will out-damage the opposing melee units if they are protected from direct melee damage themselves.

Damage Reduction or Increases for Armor
For positive Armor, damage reduction =((armor)*0.06)/(1+0.06*(armor))
For negative Armor, it is damage increase = 2-0.94^(-armor) since you take more damage for negative armor scores.

Consult this chart* for more information. A Positive Armor of 1 reduces damage by about 5.7%. A negative armor of 10 increases damage by 46.1%. A unit with 20 armor basically has 55% extra hitpoints -- 100 would become effectively 155.
