was running to thallassus and zone was buggy, i had aggro then didnt have aggro constantly , then i reached the portal near thallassus and i got snared by one of these mobs, had 3 on me, i died rather fast. my MR was about 500, so it could be chromatic or prismatic not sure
been kiting here a little lately (as a berserker it hurt, but eh).. found these , the white ones, do summon. The brown ones, prayermakers i belive, do not.
