Allows to associate spell names with sound files to be played from a configurable folder. This is done in the "Warnings" table in the options, with the first value being the name of the spell, and the sceond value the name of the sound file. Also, make sure to configure an audio channel you're actually using (the default is "Dialog" - if you aren't using that, you won't hear anything, and should set it to something else in the options).
