Pierce armor is an armor type used in the Age of Empires and Age of Empires II. Unlike ordinary armor which resists melee damage, pierce armor resists missile damage.
Age of Empires Edit
Damage formula Edit
In Age of Empires, the damage formula is:
- n denotes normal attack / armor
- p denotes pierce attack / armor
- If the target belongs to the category i and the attacker has a bonus AttackBonus against i, then the bonus (minus BonusResist if the target has one) is added to the total damage.
- k_{elev} is the elevation multiplier (applied to both cliffs and hills), equal to 2/3 if a melee unit attacks below its target, 3/2 if a ranged unit attacks above its target or 1 otherwise.
Units dealing pierce damage Edit
The following units and buildings deal pierce damage and are affected by their target's pierce armor:
- Slingers
- All Archery Range units
- Ballistas and Helepolis
- Scout Ship line
- Towers
Technologies Edit
To improve pierce armor for all infantry based units, technologies from the Storage Pit must be researched.
Age of Empires II Edit
Damage formula Edit
In Age of Empires II, the damage formula is:
- n denotes normal attack / armor
- p denotes pierce attack / armor
- If the target belongs to the category i and the attacker has a bonus AttackBonus against i, then the bonus (minus BonusResist if the target has one) is added to the total damage.
- The elevation multiplier k_{elev} is 5/4 if a unit attacks above its target (hills and cliffs), 3/4 if a unit attacks below its target (hills only) or 1 otherwise.
