Certain class features can grant you additional benefits with certain armors. This is called an armor specialization effect. The exact effect depends on which armor group your armor belongs to, as listed below.

Chain: The armor can bend with a critical hit and absorb some of the blow. Reduce the damage from Critical Hits by 4 + the value of the armor’s potency rune for medium armor, or 6 + the value of the armor’s potency rune for heavy armor. This can’t reduce the damage to less than the damage rolled for the hit before doubling for a critical hit.

Composite: The numerous overlapping pieces of this armor protect you from piercing attacks. You gain Resistance to piercing damage equal to 1 + the value of the armor’s potency rune for medium armor, or 2 + the value of the armor’s potency rune for heavy armor.

Leather: The thick second skin of the armor disperses blunt force to reduce bludgeoning damage. You gain Resistance to bludgeoning damage equal to 1 + the value of the armor’s potency rune for medium armor, or 2 + the value of the armor’s potency rune for heavy armor.

Plate: The sturdy plate provides no purchase for a cutting edge. You gain Resistance to slashing damage equal to 1 + the value of the armor’s potency rune for medium armor, or 2 + the value of the armor’s potency rune for heavy armor.
