PvP Resilience

PvP Resilience was a PvP stat that reduced damage taken from other players and their pets and minions. It is the counterpart of PvP Power, which increases damage dealt and healing done to other players. Resilience affects only damage taken from players, and is of no benefit against non-player characters.

PvP Resilience was discontinued as a stat with Warlords of Draenor, with changes made to stamina, class balancing, and PvP gear itemization in order to balance its removal. After patch 6.0.2, PvP Resilience could only be gained through various low level external sources, primarily enchantments, gems, PvP rewards and PvP heirlooms. These sources were gradually removed or converted to other stats over the course of the Battle for Azeroth expansion, and PvP Resilience can no longer be found in game.

Formulas
One percent of resilience reduces damage taken from all player attacks by 1%.

As part of the combat rating system, the amount of resilience rating needed to get a certain amount of resilience increases with level. A higher level player will need more resilience rating to get the same effect as a lower level player. At level 90, players need 310 resilience rating to get 1% of resilience.

History

 * Resilience was introduced with World of Warcraft: The Burning Crusade as part of the new combat rating system. Previously, no such resilience mechanic existed — as a result, resilience rating only appears on items available to players over level 60, with some rare exceptions.
 * Prior to patch 4.0.1, resilience reduced the chance to receive a critical strike, with 1% resilience giving a 1% smaller chance to be critically struck.
 * In patch 5.3.0, resilience was removed from most gear and innately given to characters.
 * In patch 6.0.2, base resilience was removed.
