Ever getting annoyed when using Magic Circle vs Evil? With all those sounds playing every single time someone gets near you?
If yes is the answer, then this "fix" is for you.
It will prevent sp_abjuration_conjure.sef effect (that includes the annoying sound) to show every time someone gets close to you, if you are under effect of Magic Circle vs Evil or Magic Circle vs Good.
For installation, just unzip downloaded visualeffects.2da file to your Override folder.
NOTE:
Since this is fixed with 1.23 patch, this fix is now Obsolete.
