I'm looking for a mod that removes or disables the "capping" applied to the player's attributes, skills, and level. Is there one that does exactly this (and nothing else), or is there a way to create it on my own?

There is this one.

There is also another one:

This is full configurable (you can also set the limit to, example, 207)

Ah........no. As I said in the first post, I'm looking for a mod that doesn't do anything more than uncap the limits on attributes/skills/level. This "AV Uncapper" appears to make a lot of changes to the game which I feel are quite unnecessary.

As I said, it's full configurable.
You can disable everything and only keep 3 features:
- Attributes uncapped
- Skills unkapped
- Level uncapped

I suggest this because this is recent (and supported, if you there are trouble)

I would love a mod that CAPS skills (like ROM does). Opposite of what you are looking for so sorry for hijacking your post

No mod just uncaps skills or attributes, because with one or two exceptions skills and attributes over 100 do nothing. You can set them to higher values in-game already, but the formulas that use them are also capped. Furthermore, if they weren't capped, some skills would become literally broken at higher values; for instance, spell magicka costs go negative at 117 skill. Making a lot of changes to the game absolutely is necessary if you want uncapped skills to be more than cosmetic.

Sort've like a SuperEgo of attributes?

Couldn't resist based on your sig

There is a new kid on the block that looks very promising av uncapper http://www.gamesas.com/index.php?/topic/1157256-relz-av-uncapper/page__p__16953244__hl__av+uncapper__fromsearch__1#entry16953244
It's worth a look

:)

In my game I use Wrye Leveling so no skills advance and no levels advance until I buy a level up. This allows me to get to whay I figure is the optimum level to keep game challenging which is 25. I would use another leveling mod if I could cap the levels of skills so I would have a smoother progression, but until I do I can only use Wrye Leveling. ROM has such a system but I do not want to use OOO and ROM requires it.
