With this addon you might be able to reduce the times you surf on lava waves.
If you still miss a lava wave coming with this enabled then you are a true surfer!
The default sound warning is Ekyz from Ensidia calling out for Lava Waves in a rather obnoxious manner.
You can change that by replacing the "lava_wave.mp3" in the addon's sound folder. Just make sure you keep the files name "lava_wave.mp3"
