Here are the items I’ve accumulated from the 85 scenario. After 25 attempts, I have all four caster items on my priest.
Shoulder: Mantle of the Oracle
Chest: Vestments of the Oracle
Belt: Councillor’s Sash
Gloves: Gloves of the Messiah
Feet: Footwraps of the Oracle
Weapon: Archmage’s Staff
I thought the staff was a nice addition to the set I was already wearing.
Shoulder: Wrap of the Valley Glades
Chest: Rift Stalker Hauberk
Belt: Tol-Vir Hereditary Girdle
Gloves: Lightning-Charged Gloves
Legs: Lightning-Charged Legguards
Feet: Captain’s Boots
Weapon: Marine’s Rifle
This is also the set I’m wearing on my hunter right now.
