Physical Resistance Rating

Overview
Physical Resistance Rating (abbreviated PRR) is a form of damage mitigation was that introduced with Update 14.

It provides a percentage reduction in physical damage (bludgeoning, slashing, and piercing), and is granted through multiple sources (items, feats, enhancements) and stacks with itself. Multiple effects granting an Enhancement bonus to Physical Resistance do not stack. Character sheets show the Physical Resistance Rating of the player next to the elemental resistances.

PRR is applied after damage reduction. The PRR is applied to the damage that passes through the DR and is always rounded down. As such If a player would take 20 damage before DR or PRR and has 10 DR and 60 PRR (37.5% reduction), the result is:
 * (20 - 10) * 37.5% = 3.75 rounded down to 3
 * 3 damage is resisted

Note: Monsters usually don't have PRR.

Formula
The formula for calculating damage mitigation for physical damage was changed in Update 23. The new formula is: 100/(100+Rating). Incoming damage is multiplied by this number.

Example: A character is hit for 100 points of damage.
 * 0 PRR takes full damage, 100 points.
 * 20 PRR takes 16.67% less damage, 83 points.
 * 100 PRR takes 50% less damage, 50 points.
