This mod should remove all the effects that the sustained effects use, and therefore it should give you some performance boost in game combat.
Just place the small file in your override folder, usually located in your documents.

If you want to get glowing eyes for your blood mage I do recommend that you go and download kurniallah2412's mod called Blood Magic Glowing Eyes, I myself will check that mod out daily for improvements and hopefully red glowing eyes since it currently only have blue glow effect.

Anyways, since I actually spent some time on this mod, and most likely will spend more due to its probability to become buggy, I do want some credit if you plan on taking it and using it in your own mod or if you are to upload it to another site.

If you run into any bugs or problems just let me know about it in the comment section, I'll try to do my best to help you out. Also if you got some suggestions as to how I should improve upon this mod let me know!



*UPDATE*

I made this mod compatible with kurniallah2412's mod called Glowing Eyes for Hawke. It's a great mod that I'm using, and I love it! It's amazing how such a tiny thing can have such a huge impact. It'll make you think that your blood mage actually is powerful and something to be feared. Combine his mod with my Additional Spells mod and you're ready to drain some blood and blow up some corpses!!
Enjoy, and happy gaming fellas :D
