Yesterday I found out that these level 46 mobs are immune to snare and they summon. They hatch when you kill a Deadly Armadillo. Somehow these baby armadillos learn to speak "Player name, you will not evade me!" within seconds of being born.
These hit for a max of 149. Had 2 druids and an ENC with us and 3 spawned so they all got DC pets. Talk about assing some serious DPS to a group. Very nice!
These spawn on the death of a big Dustrunner. Anywhere from 1-4 can spawn.
They can be Dire Charmed (AA ability) by Druids and Enchanters. They hit from 50-125ish. At least, that is what they hit a lvl 65 cleric with ac 1300ish for. :) Enjoy.
