Okay, so the forum ate my post, again! Arrg! So I had to retype this on my word processor and paste it in here. Hopefully this works this time . . . damn forum is acting up today.
Well, like the old saying goes, you can give a man a fish and feed him for a day or teach him to xEdit and he can fine tune his own game to suit his own personal tastes for a lifetime.
You don't actually need Skyrim's editor (the Creation Kit) for something like this. The easiest way to make this type of patch is with a program called http://www.nexusmods.com/skyrim/mods/25859/?. You should get xEdit anyway because that's what you use to clean mods, but it can do so much more than that. XEdit can show you each record that is altered by each mod in a spreadsheet format, with individual records appearing in rows and individual mods altering those mods in columns. Only the last mod (i.e., the mod in the column on the far right of the screen in xEdit) altering an individual record will have any effect in game on that record, so you can use xEdit to identify mod conflicts and create patches.
Here is a http://www.nexusmods.com/skyrim/mods/25859/? to the latest public version of xEdit (aka TES5Edit). Here is a link to an excellent https://www.youtube.com/watch?v=CQi7vnqXySc of how to use xEdit and here is one for how to use it make https://www.youtube.com/watch?v=LyDpP96LRmA. Basically, all you want to do is find the record for the archmage robes and make a new mod that contains the record from Skyrim.esm (rather than the record from USLEEP) and then save that record into a new esp that loads after USLEEP to overwrite the changes to the archmage robes made by USLEEP. While you are at it, you can see if other mods alter the archmage robes and pass through any of those changes you want.
After you have installed xEdit, you will want to run it as administrator (right click on it and select "run as administrator"). Then xEdit will show you a list of all your mods. For this patch you will want to load up all your mods so you can see if any others are altering the record for the archmage robes. So, just click OK and let xEdit load up all your mods.
Then you will want to find the record for the archmage robes. You could hunt and peck through the hundreds of thousands of records. To do that, click on the plus box next to Skyrim.esm to expand and then scroll down to the Armor (ARMO) records and then click on that plus box and scroll through all the records until you find the archmage robes.
Or you can take a shortcut and just type in the formid for the archmage robes in the box on the top left and hit return. You can get the formid by googling the http://www.uesp.net/wiki/Skyrim:Archmage for the archmage robes. The formid is shown in parenthesis at the top right on that page (0010f570). So type in 0010f570 in the box for formid at the top left of xEdit and hit return.
That should take you to the record for the archmage robes, which should be highlited in the list on the left with columns on the right for each mod that alters the record. The columns show you the changes each mod makes to the record, but only the record from the last loaded mod (the one in the column on the far right) will have any effect in game.
What you want to do now is right click on the record for the archmage robes in the list on the left and select “copy as override” from the popup menu. Then you will get a popup menu asking what mod you want to copy the record into. Select the “new” checkbox at the bottom. Then it will ask you to enter a name. You can type in your own unique name for your mod. Something like “Sybelius Archmage Robes Tweaks” would be fine, or whatever you want to type. You will also be asked if you want to add Skyrim.esm as a master, and just click yes or OK.
Now you should have a new column on the far right with the name of your new mod at the top and the data in the column should be the same as what is in the Skyrim.esm column. At this point you could just close xEdit and it will ask you if you want to save your mod. Click Ok or yes to save your mod. Then you just need to load it later in your load order than USLEEP.
(Don’t clean your new mod with xEdit since your mod contains an intentional “identical to master” record, otherwise known as an ITM. An ITM is simply a record that is identical to one of its masters. In this case, what we just created is a mod with a record for the archmages robes that is identical to the record for the archmage robes in Skyrim.esm for the purpose of overwriting the record from ULSEEP. If you clean your new mod, it xEdit will remove the ITM record. So don’t use xEdits automated cleaning on your new mod. Generally patches like this should not be cleaned for ITM records because patches like this frequently contain intentional ITM records, but cleaning for UDRs is always safe.)
But before you close xEdit, you might want to take a look to see if there are any other mods that change the record for the archmage robes and pass through any of those changes if you want to see them in your game. To see what changes other mods are trying to make for this record, look to see if there are any columns for the archmage robes record other than Skyrim.esm and USLEEP. If there are, you can peruse these columns and see what changes these mods are trying to make. If there is a change you want to keep, you can click on the change and drag it to the right into your new mod.
Remember, only the record from the last mod loaded (i.e., the column on the far right in xEdit) will appear in game. All the data/changes shown in xEdit in the other columns is just informational so you can see what each mod is trying to do and patch accordingly; none of that will appear in game unless you drag it to the right into the last mod loaded.
You can edit all sorts of stuff easily in xEdit. One example is you could change the strength of the enchantments on the archmage robes by simply editing the numerical value for strength of the enchantments. To edit a numerical value, just right click on it and select edit. Then type in the new value. You can also add new enchantments, change the enchantments, etc. etc. xEdit is a very versatile tool that you can use to edit and even create mods.
It can take a little while to get comfortable with xEdit but once you do, you can fine tune your game to meet your own particular tastes. Good luck and let me know if you have any questions. Also, if you are using Mod Organizer, you will need to google how to install and launch xEdit from Mod Organizer. I don't use Mod Organizer myself since I prefer Wrye Bash. Good luck!
