I usually don't play Oblivion on the PC anymore, but more recently I've wanted to see if there are any mods that would allow me to make my D&D 3.5 OP character. Is there anything for a mod for telekinesis that can allow you to use it in ways that you would use Master of the Unseen Hand? Also, I'd like to see a spell like Leomund's Secure Shelter as well

Anyone have any suggestions?

Try this for a new use for Telekinesis. http://www.tesnexus.com/downloads/file.php?id=22957

There's also Oblivion XP that converts Oblivion's levelling system to be more like D&D games. There are also some magic overhauls like Supreme Magicka and LAME that add new spells - not sure if they have what you'd be looking for or not.

Don't know those spell names, but Midas Magic adds many new spells to the game that are very distinct from the vanilla spells. Also, Unnecessary Violence allows any projectiles to cause damage (hence Telekinesis is more useful, if I understand correctly - smack someone with a dropped battleaxe, and there is damage dealt accordingly).

I cant believe Fearsome Magicka has not been mentioned! It adds some VERY cool new spells (especially some telekinetic ones) and uses a DnD 3.5 edition stlye magic system. Check it out!

also for additional DnD goodness, try the sam modder's Voice mod with voices from Baldur's Gate itself (very fun and immersive)
