I'm wondering something. I'm currently playing a mage, and I like the bonuses that robes give. I was wearing the cultist robes for a while because at the time, that was the best thing for me. Now I'm finding other robes that are better while more enhancements, but I don't like the look of them. I really like the look of the cultist robes. Can they be enhanced at all? Sorry for the stupid question, but I don't know a whole lot about enchanting and such. I never got involved in it. The robes are 75% faster magica.

Oftentimes I don't really care what a character looks like, but these robes really fit the character almost perfectly.

Items with an enchantment already present on them cannot be re-enchanted to make them better. If you just like the look of the robes but want an unenchanted version that you want to enchant with something other than the regenerate magicka you'd either have to add in a base robe item via the console (which may not exist) or have a mod that added in the basic robe item without an enchantment present on them. Both of these options require you to be playing on the PC, if you're on a console sorry but this won't happen.

Thanks. As far as I can tell, these robes are unique and an unenchanted version does not exist. I could probably do something with the CK on it, but it's not worth it to me right now. I'm playing on PC.

You should be able to find a mod. Immersive armors adds a ton of clothing that you can craft ( at least I thin it is immersive armors).
