Oblivion XP Update

Version 4.4.5

Oblivion XP Update is a full update to SirFrederik's Oblivion XP mod. It has several bug fixes and script optimizations that utilize the new features and functions available in the newer versions of Oblivion Script Extender. This version offers significant performance improvements over the previous versions.

This is a complete self-contained package. It does not require the original Oblivion XP - everything is included in this update. This is being released as an upgrade to the original Oblivion XP mod because the changes are quite extensive and with most of the scripts being completely rewritten.

Existing users will be able to install this update and continue with your current games. You should not lose the progress you have made. You will need to follow the upgrade instructions in the readme file because the location and contents of the ini file have been changed.


For those unfamiliar with Oblivion XP, it is a levelling system replacement. The Oblivion levelling system is based on skill use to improve the skills themselves and their associated attributes. However, for many players this has turned out to be a tedious exercise that forced them to use skills that did not fit their roleplaying experience in order to improve certain attributes. It also required a certain degree of "micromanagement" if you wished to get the maximum attribute bonuses when you increased in level.

Oblivion XP aims to change all that. It brings the experience point reward system to Oblivion. You gain experience points for performing a variety of actions, including completing quests, killing monsters, picking locks or discovering new locations. When you accumulate enough experience points, you will gain a new level. Upon gaining the new level, you spend points to increase your attributes and skills. You no longer improve your skills by using them. You earn experience points by action and spend an allotted number of points on skills and attributes to improve them, anyway you wish, when you level-up.

SirFrederik is the original author of this mod. He devised the mathematical formulae that control the number of points you need to level and the number of experience points you receive for various actions. The system he designed is complete and operates as a balanced and comprehensive unit. I will not be altering any of this underlying logic. He also made Oblivion XP extremely customizable through settings in the ini file so that this system would work with a variety of playing styles.

Important Notes

Oblivion XP 4.2.0+ requires OBSE 21 Beta 3 or above. shadeMe has added a custom event handler that allows major performance improvements over the previous versions. It also requires MenuQue version 15 or newer.

See the readme file (Oblivion XP Readme.pdf) in the download for the installation instructions, a full description of all the changes and other important notes.

Oblivion Script Extender (OBSE) v21 or higher
MenuQue version 15 or higher

Friends of Oblivion XP

Friends of Obivion XP is a prestigious group of mods in which the mod authors have taken the time to build Oblivion XP support into their mod!

When you complete quests in these mods, you will be awarded experience points. Oblivion XP only has a small amount of work to do to process these points, so performance is greatly improved. Also, this code is only run for mods that you actually have loaded and if the mod author changes the mod, you will get those changes as soon as you download the new version of the mod!

I will list the patches currently available in this section. Patches can be downloaded from the main download page. As of version 4.2.3, these are now optional, but if you have room in your load order, I recommend you use them. The point rewards are customized for each quest, whereas the base point reward will be much smaller.
