World of Warcraft®

Abilities cost 75% less Energy while you are stealthed.

Enter into a state of heightened awareness, deflecting enemy weapon strikes with increasing effectiveness. Successive attacks will deal 10% less damage per application, stacking 5 times.

Lasts for 20 sec, but if 10 sec elapse without any incoming weapon strikes, this state will end.

An attack that would otherwise be fatal will instead reduce you to no less than 10% of your maximum health, and damage taken will be reduced by 80% for 3 sec. This effect cannot occur more than once per 90 seconds.
