guardian wurm  

A 65 cleric, a 65 druid (me), and a 65 Shadow Knight fought these. Hit me in the 300s and 400s. AE was rather easy to resist. It tried to run at about 20% health but it was snared.

On it's death it spawned the 2nd version. The one that has the dispells, and AE fear. The fear was resisted rather easily, but it effected me one time. The dispells were nasty. This mob also tried to run at about 20%.

The 3 of us handled them well with no slow.
