*Ironically, this set is only completable by Alliance members. This is because two of the pieces are the T9, which have different models for the Alliance and Horde.
Head: Malfurion's Headpiece of Conquest (Cover/Headguard)-Purchased from T9 vendors at Argent Tournament
Shoulders: Ruthless Gladiator's Kodohide Spaulders (Dragonhide/Wyrmhide)-PvP Vendors in Stormwind/Orgrimmar
*The proper color is the Elite version of the Season 10 shoulders (shown in picture above), available to those with an arena rating. If you can't get them, the regular Season 10 works just fine as well (linked above).
Chest: Savage Gladiator's Kodohide Robes (Dragonhide/Wyrmhide)-Purchased from Legacy vendors in Dalaran
Shirt: Antiseptic Soaked Dressing- Bought from First Aid vendors in Dalaran.
Hands: Malfurion's Handguards of Conquest (Handgrips/Gloves)
Belt: Wrathful Gladiator's Belt of Salvation (of Dominance) -Purchased from Legacy Vendors in Dalran
Legs: None
Feet: Naturewarden's Treads- Drops from Essence of Anger in Black Temple (BC T6 Content)
Treads of the Den Mother (Drop in BT)
*I chose these because on a Night Elf, they look like hooves. :)
Weapon: Staff of the Four Golden Coins (Quest reward in Nagrand for both Horde (An Audacious Advance) and Alliance (The Twin Clefts of Nagrand) *There are multiple versions of this staff in a golden color with green and orange feathers. However, the in game NPC of Hamuul uses the silver (before he gets attacked)
Notes If you want to do a Hamuul Runetotem pre-Leyara attack simply go farm the Thunderheart Rainment (T6). Tokens are found in both the Mt. Hyjal and Black Temple raids.
