Tenacity (Wintergrasp)

This buff is applied to the side that has the fewest members in Wintergrasp during a wintergrasp PvP battle. It is applied with varying levels of stacking, with an apparent maximum of 20 stacks.


 * Characters, per stack
 * health (HP) increased by 18%
 * health regen increased by 18%
 * amount of healing received increased by 18%
 * amount of damage dealt increased by 14%
 * Tenacity is only granted to characters of level 70 or greater.


 * Vehicles, per stack
 * health (HP) increased by 18%

Theories on stacking
The algorithm for how many stacks to apply is unknown, although a previous hotfix has indicated that only characters level 70 and higher are counted.

There are proponents both for linear stacking (stacks = C * (x-y), for some value C) and exponential stacking (stacks = 10x/y). More research is needed.

Patch 4.0.3 Change

 * As of November 16, 2010 and the release of Patch 4.0.3, Tenacity no longer applies to players during the battle. This is due to the implementation of a population balancing system that maintains the population at a 1:1 ratio.  This was an undocumented change, implemented to test the balancing system before deployment to Tol Barad.
