In The Elder Scrolls IV: Oblivion , each Mages Guild hall in Cyrodiil (except Bruma) has a school‑of‑magic specialty that shapes the spells and training you get there.

Which cities have which specialties?

Here’s a clean breakdown of the Mages Guild “specialties” by city:

[7][5] [5][7] [7][5] [5][7] [7][5] [5][7] [7][5]
City Mages Guild specialty Notes
Anvil Restoration Strong Restoration‑focused training and spell selection.
Bravil Illusion Heavy on Illusion spells and Illusion‑based training.
Bruma None / general No clear specialty; more general‑purpose magic services.
Cheydinhal Alteration Focuses on Alteration spells and training.
Chorrol Conjuration Best spot for Conjuration‑heavy builds and summoning‑related training.
Leyawiin Mysticism Strong in Mysticism spells (telekinesis, soul trap, dispel, etc.).
Skingrad Destruction Top choice for Destruction‑oriented mages, with high‑quality offensive spells.

How the specialties actually matter

  • Each hall’s specialty shows up in which spells are sold and which magic school the local trainers emphasize.
  • You can still train and buy spells from other schools, but the specialty hall will usually have more variety and higher‑level options in that one school.

So if you’re asking “which Mages Guild specialties exist in Oblivion,” the answer is: Restoration (Anvil), Illusion (Bravil), Alteration (Cheydinhal), Conjuration (Chorrol), Mysticism (Leyawiin), Destruction (Skingrad), with Bruma being unspecialized.
