An Order to Hunt  

The easiest way I found to do this, is to take the Sokokar from the Howling Stones Post to the Skleross Encampment, it is out of agro range of the Skleross soldiers, then run west to the spot of the 4th update, Agent Retssok, and hidden behind the rocks is the Sleetsaber, they have a five to ten minute respawn and the Nettle spined succulents are all NON KoS so as long as you or your group don't use AoEs you should be fine getting all six updates, then you can take the Sokokar back to Howling Stones and talk to Zixka.
