Penetration is a value that represents how much of your damage will break through an opponent's armor. The higher an enemy's armor, the more of your damage is mitigated. For example, if an enemy NPC has 18,200 armor, they will resist 36.4% of your damage. A higher amount of penetration means the more armor you will break through.
There are several ways to increase this:
- Race, Class, Weapon and Armor passives, such as Hunter's Eye, Dismember, Concentration, and Heavy Weapons.
- The Lover Mundus Stone.
- Champion Point Slottables, Piercing and Force of Nature
- Additionally some sets contain Physical and Spell Penetration as part of the bonus such as Stygian and Icy Conjurer
