Oblivion:Random Skill Books

Overview

We have to read every skill book in the game, which typically adds very little time to the run given how many skill books appear in locations we already have to go to for other reasons. The only problematic ones are the random skill books, which can only be found in random loot, with few exceptions. These random books can take an excessive amount of time to find, with previous runs taking upwards of two hours to find them all.

Here is how random skill book loot works in Oblivion:

• When you enter a cell containing chests, those chests’ loot contents are randomly generated.
  • This means that quicksaving outside of a cell and reloading if you don’t get the desired loot will allow you to reroll what loot you get, at the cost of having to run back through the cell to open the chest again.
  • This also means you can save inside the interior of a dungeon, not just outside it, to reroll. For example, a dungeon with cells 1, 2, and 3 where the book is at the end of cell 2 means you could load warp to cell 3, save outside the door from 3 to 2, then reroll entering cell 2 through that door repeatedly until you get the loot you want.
• Only Boss Chests are able to contain skill books, and only certain dungeons can contain certain categories of skill book type. These are the three skill types of combat, magic, and stealth.
  • Marauder and Undead dungeons can contain Combat skill books.
  • Conjurer and Necromancer dungeons can contain Magic skill books.
  • Bandit and Vampire dungeons can contain Stealth skill books.
• After successfully locating a skill book in a dungeon, you must wait 73 hours for the dungeon loot to refresh.
  • This means it is most efficient to find one of each type of book and then wait 73 hours to refresh all three dungeons.
• There is a 10% chance that a Boss Chest will contain a skill book, and an equal chance of each book in the pool of that type of skill book appearing.
  • This means that for each skill book we find of a certain type, it becomes less likely that we will find the next book we need of that type.
  • Additionally, other skill books that are not exclusively found in random loot are also in the pool of options, further worsening the chance of finding the right book.
• Finally, a few quests can reward a random skill book:
  • Bear Season (Can be re-rolled, 4/6 chance of one of these random Combat skill books):
    • The Argonian Account, Book 1 [Athletics]
    • History of the Fighters Guild [Heavy Armor]
    • Mace Etiquette [Blunt]
    • Master Zoaraym’s Tale [Hand to Hand]
  • Two Sides of the Coin (Cannot find an easy way to re-roll):
    • The UESP has conflicting info between the quest page and the Skill Books page, so this is unconfirmed:
      • Two skill books are earned, one of which is a 5/6 chance of being one of the Stealth random-exclusive skill books. Another page of the UESP claims it is a 5/7 chance but does not specify a list of specific books.
      • The second skill book is allegedly a 13/13 chance of a random book that can be found in loot but this seems incorrect. Another page on the UESP says it is a random Magic or Combat book from a pool of all possible skill books of those types including non-random loot books, but this also seems not entirely correct.
