To get Glow Dust in Oblivion (and Oblivion Remastered), you have two main options: buy it from ingredient shops or loot it from Will-o-the-Wisps.

Easiest method: buy Glow Dust

The most reliable and fastest way is to purchase it in the Imperial City.

  • Go to the Imperial City, Market District.
  • Check these alchemy/ingredient shops:
    • The Main Ingredient (run by Ogier Georick).
* The Gilded Carafe.
  • Glow Dust typically costs around 70–75 gold per unit (about 71 gold is a common price).
  • If the shops don’t have Glow Dust in stock, wait about 72–73 in‑game hours outside and check again; their inventory will refresh.

You can also sometimes find Glow Dust for sale in Mages Guild halls and other ingredient merchants in the major cities if you do a circuit and check them all.

Farming Glow Dust from Will-o-the-Wisps

If you prefer to farm it, Glow Dust drops from Will-o-the-Wisps.

  • Common Will-o-the-Wisp locations:
    • Forests and swamps of Cyrodiil, especially at night or in foggy weather.
* Blackwood region near Leyawiin and other marshy areas.

* Around some Oblivion Gates and in certain “beast” dungeons or caves.

* Near Azura’s Shrine northeast of Cheydinhal during or after starting Azura-related quests.

How to actually kill Will-o-the-Wisps

They are notoriously annoying because normal weapons barely hurt them.

  • Use:
    • Enchanted weapons, or
    • Silver weapons, or
    • Offensive spells (especially elemental magic).
  • If you attack with a plain, unenchanted weapon, you’ll do little to no damage.

Once killed, they can drop Glow Dust, which you can then use for alchemy or as an offering for Azura’s Shrine.

Quick answer for Azura’s Shrine quest

If you’re specifically doing Azura’s Daedric quest and need Glow Dust for the offering, the game itself points you toward The Main Ingredient in the Imperial City as the “easy mode” source. Buying it there and using time-wait to refresh the shop is usually faster than hunting Will-o-the-Wisps, especially at low levels.
