Hey! This is my first post and I've been searching for any information on what might be happening in my game..

I finally started playing Skyrim recently and got into adding mods; made a few characters, ran into errors, learned a bit and finally got my game to a place I'm happy with. A couple of days ago though I noticed after getting hit a few times a weird, giant, purple orb spell would appear- turning me invisible and possibly healing me. I thought it might have been the follower Lofen the Stout (follower mod- cant post link) since I noticed it after choosing her and she was all about that lightning magic. Eventually though while fighting in Fellglow and seeing Dremora all over the place (is this normal in vanilla?) the effect would appear repeatedly and my character would just bleed out all of a sudden and freeze in place! I uninstalled Lofen and even Eryniel (another mod companion), and even recent spell teleportation spell mods, all to no avail. The ~ command feature doesn't show any information about a spell being auto cast (not sure if there's a deeper 'info-mode') and I just have no idea where this thing could be coming from..

In the photos, I aggroed a bunch of soldiers in Dragonsreach- no god mode or any OP armor/stats and a relatively low level I believe (havent even started civil war yet) and my character can almost sit through their attacks while the spell repeatedly goes off, turning her invisible and auto healing. I'm just hoping someone may have some idea or maybe see something stupidly obvious that I've been missing...

I only use NMM to install mods and have a variety from UNP textures, XP32 skeleton, SOS, realistic lighting and environmental stuff, sixlab, racemenu and armors- the effect looks similar to the Dremora summon I believe but I've never used a spell like that. Any help or directions to other tools would be very much appreciated! (Like if there's a system log in Commands that lists everything that happens) Sorry if this was too wordy and if there's anything else I could show to help you guys help me, just let me know- thank you!

(Cant seem to post images? Still figuring this forum out!)
