Berserking

From WoWWiki

For the weapon enchant, see Enchant Weapon - Berserking.

Berserking is an active racial trait of trolls. It increases casting or attack speed (depending on your class) by 20% for 10 sec. Activating this ability does not trigger the global cooldown.

Tips and tactics

Try to use this ability alongside another haste effect, as any two haste effects are more useful together than individually.
