Other than the helm, it's the lookalike rogue gear from lfr fear/terrace. Easy to farm nowadays as you can just get your lesser charms from the treasure trove scenario on isle of thunder, and the raids are fairly easy nowadays. Only had to do Tsulong twice for gloves and queen twice for the shoulders to drop.
Head: Swashbuckler's Eyepatch
Shoulder: Cultist's Bloodsoaked Spaulders HC
Chest: Savage Gladiator's Dragonhide Robes
Hands: Savage Gladiator's Dragonhide Gloves
Belt: Snow Lily Belt
Weapon: on screenshot im using Hellreaver, but now i have Blackhand Doomsaw.
Other weapons that i think would fit this: Screaming Tiger, Qiang's Unbreakable Polearm(normal), Twisted Visage or Rapture.
For tauren i don't need boots, so i don't know if there are any good for this transmog
As for the weapon... I like the simplistic look of the bear paw staff. The frostscythe is a little too much for me. Plus, the bear paw fits my idea of this "Amani Dark Druid" idea that I had for my troll. Sounds lame and RP'ish, I know, but that's where the xmog came from. If you have any other weapon suggestions that would be more suited for it and fits the color theme, please let me know!
