I'm looking for a solid mod that extends the duration of Abyssal anguish to basically infinite, I cannot find a mod to do this that installs correctly. I also don't know how to do it myself. I'm also looking for a solid mod that shortens the time for casting by quite a bit, one that installs correctly or better than the ones I've found. Any help is appreciated. If you can make one, it would be much appreciated. If not, I tried.
