This is an old set from before Blizzard decided to make their caster items more interesting. The choice of stats for sets are horrible, and could've been much much better. Unless you plan to upgrade to sorcerer's set, or have really terrible gear, do not plan your mage career around this set at any level. There are many many individual blues which together trumps anything this set can offer.

The Magister's Regalia Set pieces drop from Stratholme, Scholomance, and Blackrock Spire.

Head: Drops off of Darkmaster Gandling in Scholomance
Shoulders: Drops off of Ras Frostwhisper in Scholomance
Chest: Drops off of General Drakkisath in UBRS (Upper Blackrock Spire)
Wrists: Drops off of various mobs in BRS (Blackrock Spire)
Hands: Drops off of Doctor Theolen Krastinov in Scholomance
Waist: Drops off of various mobs in Scholomance, Stratholme and BRS
Legs: Drops off of Baron Rivendare in Stratholme (Undead side)
Feet: Drops off of Hearthsinger Forresten in Stratholme (Scarlet side)

Also, the Belt, Bracers, and Gloves are Bind on Equip, whereas everything else is Bind on Pickup.
I hope this helps.

This is the Mage Dungeon 1 set, collected in 60th instances pre-tbc. They are used to upgrade to Dungeon 2, and the other sets are:

https://vanillawowdb.com/?itemset=181 Magister's Regalia - Mage (Cloth)
https://vanillawowdb.com/?itemset=182 Vestments of the Devout - Priest (Cloth)
https://vanillawowdb.com/?itemset=183 Dreadmist Raiment - Warlock (Cloth)
https://vanillawowdb.com/?itemset=184 Shadowcraft Armor - Rogue (Leather)
https://vanillawowdb.com/?itemset=185 Wildheart Raiment - Druid (Leather)
https://vanillawowdb.com/?itemset=186 Beaststalker Armor - Hunter (Mail)

https://vanillawowdb.com/?itemset=188 Lightforge Armor - Paladin (Plate)
https://vanillawowdb.com/?itemset=189 Battlegear of Valor - Warrior (Plate)

REMEMBER: These don't have class restrictions. You can use any that you can, but the stats are tuned to the particular classes. You also require your class's set before upgrading to Dungeon 2.

Set looks really nice, it's one of the few old style good looking armor sets and deserves to be add in collection of Role players, especially if you are RPing a mage character. Though keeping the whole set takes a lot of space in bank.

<b>Wrist, Waist, Hand</b> items can be bought from AH, they have a high drop rate and BoE.
<b>Shoulders</b>, <b>Head</b> items also have a good drop rate, I looted them in my first run in Scholomance. <b>Feet</b> item is a bit harder, cause Hearthsinger is a random spawn NPC in Stratholme sometimes it takes time to find him. <b>Legs</b> item is also drops from Baron in Stratholme and a bit harder than others. But the hardest one is <b>Chest</b> item which drops in UBRS, and the drop rate is almost equal with other D1 Chest items which drops from same Boss and you might try a couple of times to get it.

Yet it worths your trouble if you like old vanilla sets, and it's not really hard to gather them if you're farming at high levels or getting help from a high level player.

If you want to actually use it for playing and levelling, It won't take you far, cause they'll be replaced at your first quests in Outland, and if you're not planning to keep them for later, it's not worth the trouble.

Enjoy.

An item that would provide an effect similar to the 6 piece set bonus is the https://vanillawowdb.com/?item=942 Freezing Band .

<del>To clarify (since I was wondering myself for a long time), the BoE pieces of this are still available but the BoP ones are not, that's why the entire set is listed as <i>No longer available to players</i>. The wrist, belt and gloves are still in the game. They were presumably left in to stop them from becoming obscenely overpriced rarity items in the AH with people still having them saved, unbound, in their banks, as I did; people who already have them can use them without feeling like they're missing out on a Hyacinth Macaw amount of money, knowing that they'll drop again and remain stable in the economy.

edit - for the love of god. I tire of saying it, but if you're going to downrate a comment for inaccuracy or redundancy, reply with corrections so that you're improving the sum usefulness of the comment feed rather than eroding it. <i>Silent downrating is stupid.</i></del>

This seems to be incorrect. None of the dungeon pieces are dropping any more, but existing BoE and BoP pieces remain in the game unchanged.

Old sets like this one will be available from Darkmoon Faire Island in 4.3 patch(minor details might not be accurate).
