Lingering Rage

Rank 5/5

Increases the time before your Rage begins to decay after leaving combat by 10 sec.

Doesn't change the damage or healing of any Warrior spell.

Averages, counting crits and misses, for a level 60 Warrior with a typical weapon and no other gear or buffs, against a target your level. Worked out from the game's own data, the same way as the Foresight addon.
