Hiya! Im XAngelMoonX, the creator of CV (Cosmic Variations) and AlphaSounds0.17! I would like to ask you a question, are you on the Dicecord? (Dicey Dungeons Discord Server)
If not, I would like to get you a link to it.
And if you are, please chat to us in the #modding chatroom to help with a smooth development of your mod, there are a lot of talented people that are willing to help in any way possible.
Either way, have a good day, and good luck with your mod!
One more thing, we can talk about how to add soundevents, you can look at CV or Alphasounds on how to add Soundevents, since they add new tracks for bosses and basic combat.
