These mobs are found in pairs, and call non-elite adds when engaged.  

Attacks and abilities
The Guardians have a Rend ability. They hit cloth for approximately 4,800-5,200, with crits in excess of 11,000.

Strategies
These mobs are immune to snares, polymorph, and fear. The first pull with the Guardians also pulls the Amani'shi Savages, but if the Guardians Reset, the Savages do not necessarily reset.
