In Skyrim, can I get my companion to change robes?
Solution 1:
If you AREN'T on the pc, the only way to get J'zargo to wear those robes (as I did on my xbox 360) is get pickpocking to 100 for the "PERFECT TOUCH" perk which allows you to steal his default armor and thus allow him to wear the archmage's clothes, that's how I got it anyway.
Solution 2:
If you are playing on PC, there are several answers to this question you might find helpful. Notably:
You can remove all of your companion's default armor by opening console with the ~ key above tab on your keyboard then by clicking on your companion, in which case Lydia, and typing removeallitems and pressing enter. Now you will be able to place what ever you want on him/her. As a warning, if you remove their armor & weapons they will lose their infinite arrows and you will need to replace them every time she/he runs out.
Important: Make sure to remove all items from your companion's inventory before doing this because you will lose them!
and...
If you are on PC, TCG Tradable Companion Gear might help you out.
The second being a link to a mod that let's you liberally change whatever gear your followers are wearing.
Solution 3:
give her the items, open the console, click onto the follower and type:
showinventory
you should now see a list of all items plus their id-codes. Now just type:
removeitem [id of the item] [number of items to remove]
so it should look something like removeitem 0004a26b 1
Note: This id is just some creation of mine, i've got no idea what object it could be.
The id is a hexadecimal (contains a to f) number of 8 characters.
This way is better than removeallitems, for you can pick those items you want and trading items to follower seems to reset theit default equipment.
Solution 4:
If you're on PC, you can use the console for this, much like most other Skyrim problems. If you're on Xbox 360 or PS3, you're probably screwed, much like most other Skyrim problems.
In the console, you can type help "Archmage's Robes"
to get the item ID of the Archmage's Robes (or any other items you may want to equip to people later).
For the Archmage's Robes in particular there are two different versions (quest outcomes I guess?). Without +50 magicka its ID is 0007C932
, and with +50 magicka it's 0010F570
. Then you can open up the console, click on J'zargo, and type equipitem 0010F570
to equip the robes on him (or the other ID if you have the other version).
If he doesn't have the robes in his inventory, or if he has the wrong version, that command will actually conjure up a set of Archmage's Robes out of thin bytes and give and equip them to him.
