As a returning player and in the midst of re-leveling my favorite class, a Necro, these things **** me off to no end. They are not KOS to my Dark Elf Nec, but do con dubious, and they ARE social and will pull others with them if they are close enough to each other.
They cast some stupid healing spell when they get around 20-30%, and it heals a good 10-20% of their health back, and they cast it OVER and OVER again. So unless you can burst them down really quickly, they can be a huge pain in the *** and I even quit the quest I was working on that involved killing 5 or so of them because of dying multiple times to them.
Even though they are low level and I basically just skipped over them and onto the quests in Stone Hive, these mobs annoyed me more so then most every other one I have encountered in my years of playing EQ. Have fun! :P
