This look is probably my favourite of all transmog sets so far, featuring the [Valorous Nightsong Spaulders] (why do druids get all the nice gear?) from the druid tier 8. I put this set together for my friend and helped him farm it, and I think his night elf druid Illthiá looks awesome in it!
This set is mainly a mix of druid tier pieces; the chest, legs and shoes are from the t2 Stormrage set, while the head, shoulders and gloves are parts from the t8 Valorous Nightsong set. A brown belt and a green or white haircut makes this outfit complete. My weapon of choice would be the [Draenic Wildstaff], but since my friend had a dagger equipped we went with a matching PvP-dagger and one of the off-hands available for purchase from the Justice point vendors.
