Viper Sting (hunter ability)

Viper Sting applies a poisonous sting that drain 4% mana over 8 sec (up to a maximum of 8% of the caster's maximum mana). Only one Sting per hunter can be active on any one target.

Improvements

 * Efficiency (hunter talent) (Marksmanship Talent): Reduces the mana cost of your Shots and Stings by 2% per rank (5 ranks total).
 * Improved Stings (Marksmanship Talent): Increases the mana drained by your Viper Sting by 6% per rank (5 ranks total).
 * Hawk Eye (hunter talent) (Survival Talent): Increases the range of your ranged weapon by 2 yards per rank (3 ranks total).

Tips and tactics

 * When used with wound and deadly/mind numbing poison it's very annoying for a priest in PvP, especially if they're not specced holy.
