Harvest 10-15 the hand of nife to get Rodcet Aloe. The quest can be deleted immediately and re-obtained if you wish to have to harvest fewer to complete.
Note: These are unique harvesting nodes found all around the Vultak Scavenging Site island ( -630, 0, -70 ) /waypoint -630, 0, -70. It doesn't take long to find them, but you will have to cope with the vultaks on that island (level 60-62). But if you are VERY careful you can invis up to them and harvest all you need without ever fighting. You might need to make 2-3 rounds of the island.
Note: Occasionally one node may be harvested multiple times, at a max of up to three (3) times.
Return to the Hidden Shelter, and speak to Surgeon Kweezil for your reward.
