At first sight, this spot may look a bit daunting with so many mobs crowded around the centre but unless you've taken a different history, the sarnaks will not agro. You can even pull the undead through the sarnaks, though don't use AoE spells...
I was boxing a pair of 115 mages. Buffed myself up and pulled a skelly from the centre, 5 came but it was no big deal, 2 air pets and swarm pets took them down ok.
Came back later and Kra`du was up. Same tactic, boss and 4 adds this time. Kra`du didn't seem to be any more trouble that the adds, more HP but I didn't notice any special effects hit us.
That's another Hunter zone done...
