The Oghma Infinium is a book which is obtained upon completion of Hermaeus Mora's Daedric Shrine quest. When you read the book, it increases three skills and two attributes by 10 points each, permanently. Which skills and attributes depends which of three paths you choose when you use it. You may only choose one path, then the book disappears. The choices are as follows:
|The Path of Steel||The Path of Shadow||The Path of Spirit|
|Strength||Speed||Willpower (see bugs)|
Skills can be increased above the usual maximum of 100 points. This is of limited use, however, because skill increases over 100 do not grant special abilities and usually do not increase damage/armor rating/spell effectiveness etc. One advantage is that you are able to gain extra levels if the Oghma Infinium raises major skills.
Using this book, all attributes except Endurance, Personality and Luck (but only two of them per character, depending on which Path you choose) can be raised above 100 to at most 110 with a corresponding increase in all derived values, such as Magicka, running speed or carrying capacity.
- The text inside is identical to the text in the Mysterium Xarxes.
- Although your attributes are increased by 10, you are not notified of the increases in the upper left of your display in the same way as you are for the skill increases. This is because the game handles the attribute changes differently; it checks what your current attribute is, then adds 10 to it.
- If the skills raised by the Oghma Infinium are major skills to you, they count to raise your level. This means that if more than one of the skills raised are your major skills, you will raise your level more than once. If this happens, the first level increase receives the attribute bonuses that you get per level as normal. However, if you obtain a second or third level increase, subsequent level-ups only allow +1 attribute gains each.
- The Oghma Infinium is considered a quest item and cannot be removed from your inventory, except by giving it to Martin in Blood of the Daedra or reading it.
- You do not have to read the Oghma Infinium immediately. If you want to boost your attributes above 100, you can wait until you have finished training the attributes and then read the book.
- In Irish mythology, there exists a god called Oghma, whose domains include knowledge, writing and speechcraft; Infinium resembles the Latin infinitum, meaning "infinite". Thus, possible meanings of "Oghma Infinium" could be "endless writings" or "infinite knowledge".
- Taking the Path of Spirit does not properly increase Willpower, because the script tries to raise it as a skill.
- This bug is fixed by the Unofficial Oblivion Patch.
- An alternative console code is
player.setav willpower #(# = what your willpower should be). This specific command is slightly easier to use, however you must unequip all Fortify Willpower items to use it correctly.
- However, the easy way to do this without going through the hassle of unequipping anything is to use
player.modpca willpower 10which will increase willpower by 10.
- On the 360 and PS3, no current patch fixes this problem, making the Path of Spirit far less attractive. Increasing skills above 100 does not decrease casting cost.
- Attempting to activate the Oghma Infinium may trigger a bug whereby the game freezes upon activating the skill boost. A workaround for this is to assign the Oghma Infinium to a shortcut key. Activating the book using a shortcut key, rather than by selecting it from the inventory, will allow the player to gain the skill boost as normal without the game freezing.
- SloCans Oghma Infinium Crash Fix may fix this problem.
