Goblin

Overview
"Goblins are small, seemingly-meek creatures that inhabit Archos' many forests. If you underestimate them, though, you may find yourself knocked out and stripped of all your belongings. They are clever little thieves, but they aren't cold-blooded murderers - they would dare kill another living creature."

Description
Goblins apply a high amount of Constitution damage when attacking and will knock you out and take all of your gear. Rest easy though as they will hold onto your gear for some time before stashing it in a goblin treasure chest nearby, however such chests can be looted by other players even on PvE servers. They are known to sometimes knock out and leave other wild creatures attacking them that can be tamed.

You need to tame Goblins to craft Goblin Gizmos in their inventory as you cannot do it yourself. The Wooden Clubs they drop are great tools to tame some creatures with cobweb slow as long as the creature has enough health. Bear in mind not to use clubs on knocked out creatures though as it decreases their bonus levels. As Wooden Clubs cannot be repaired by the players themselves it is another reason to hunt these green cheeky fellows.

They prefer cooked meat in terms of taming.
