In Nax
Each of the main bosses of a wing drops two tokens, while the other bosses drop one token. The armor slot a particular boss drops will always be the same. The lesser bosses in a particular wing will drop the same armor slot, with the exception of the Abomination wing which has 4 bosses instead of the usual 3. In the Abomination wing, the third boss (Gluth) will drop one token that any of the other lesser bosses can drop. Kel'Thuzad drops the ring to complete the set, and no turn-in is necessary.
The four "minor" pieces of the set all drop from the first two bosses of the wings, plus all four pieces have a chance to drop from Gluth:
Waist: Plague Wing (Noth, Heingan) or Gluth
Shoulder: Abomination Wing (Patchwerk, Grobbulus, Gluth)
Wrist: Spider Wing (Anub'rekhan, Faerlina) or Gluth
Feet: Deathknight Wing (Razuvious, Gothik) or Gluth
The four "major" pieces of the set all drop from the main boss of a wing. Each of these bosses will drop 2 tokens:
Head: Thaddius (Abomination Wing)
Chest: The Four Horsemen (Deathknight Wing)
Leg: Loatheb (Plague Wing)
Hand: Maexxna (Spider Wing)
The materials needed in addition to the token vary by class and armor slot. Each set item requires a certain amount of "wartorn <armor class> scraps" (e.g. cloth wearers need "wartorn cloth scraps") which drop off of the trash mobs in Naxx. The amount required for each armor slot:
Head: 15
Shoulder: 12
Chest: 25
Wrist: 6
Hand: 8
Waist: 8
Leg: 20
Feet: 12
For a total of 106 for the entire set.
In addition to the token and scraps requirement, the hand-ins will also require quantities of two of the following five items:
Mooncloth
Cured Rugged Leather
Arcanite Bar
Nexus Crystal
Arcane Crystal
And this is a teaser of waht our next set after that will look like
