Gruoks are sick. I have tried killing them as a Mage, a druid, and a tank, and unless they are 7 to 10 levels below me they kick my butt. I think the problem is that they can pretty much spam their special attacks and do WAY too much damage compared to their level. Even my tank character (Half-Giant Warrior in plate) can not take more than a few hits, even though I have a few cleric so I can heal a bit.
I think they either need to do a lot less damage or have a lot fewer hit points so they can be killed faster before they tear people up.
Thanks!
