The Woodsbeast Garb set is an armor set specific to Goblin regions. The set consists of six armor pieces (head, chest, legs, shoulders, gloves, boots) that must be equipped at the same time. It is unlikely you will acquire a full set prior to finishing the game or reaching level sixty. Farming levels in Fazeer's Dun'djinn (the end game) that give a +50% gear luck modifier will be your best bet in finishing up the set. Any level with a flame icon on the card appears to count as a goblin level. Set pieces can be acquired through the gambler.
