**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*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._{elev}

### 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

### Damage Formula Edit

In *Age of Empires II*, the damage formula is:
