Pierce armor

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
• Ballistae and Helepolises
• 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.
