I was wondering if any mods made it worthwhile for a mage to wear a robe? I often find myself wearing armor for increased damage protection which is OK for a battlemage I suppose but I was wondering if there was anything that made robes especially useful.

Well, there's my mod Fizzle... which makes not wearing a robe rather painful.

Interesting, I may take a look at that.

I highly recommend this little bit of awesome; http://www.tesnexus.com/downloads/file.php?id=18875 and it's OOO patch http://www.tesnexus.com/downloads/file.php?id=20728. Since this mod replaces a large number of Oscuro items, you should use BAIN install for ease of book keeping. The leveled lists all work (so far as I can tell). However, this mod does not play nicely with Cyrodiil NPC Remodeling Project, which also replaces or usurps a bunch of OOO stuff. Really, this mod is the best loot for magic users that I have ever found.

Edit 1: ME also replaces the robes of Mannimarco. If using Mannimarco Revisited, you'll have to decide which mod has priority.

I don't use any of those mods you listed Immortal-D so I will check this out as well thanks!

OOO also makes wearing robes worthwhile as it ups the spell efficiency penalty for wearing armor. Plus it has a couple of robes that are really worthwhile, i.e. have enchantments that are much better than the PC can make by enchanting them.
