Vashj'ir Honor Guard

Vashj'ir Honor Guards are naga found in Serpentshrine Cavern in Coilfang Reservoir.

Abilities

 * Execute - Attempts to finish off a wounded enemy, inflicting normal damage plus 200. Execute can only be used on enemies that have 20% or less health.
 * Frenzy - Increases the caster's attack speed by 60% and the Physical damage it deals by 50 for 10 min.
 * Knockback
 * Mortal Cleave - Inflicts 80% weapon damage and leaves the target wounded, reducing the effectiveness of any healing by 50% for 8 sec.

Immune to stuns and crowd control. Has a knock-up-and-slightly-backwards ability; while tanking beware of any mobs that have not been cleared behind you, especially on the first group if Hydross the Unstable mobs are still around.

Strategies
Warriors should use Berserker's Rage at 40% to avoid aggro loss due to its Intimidating Shout.

Speculation

 * They likely come from Vashj'ir.
 * It is possible that they are the Naga Royal Guards that accompanied Vashj to Outland.
