FORTANO ORDIGUMA! ;)

@Asturias Have you tried the NWN Vault version?

I switched to english langage and it worked

I've only had one time when the sounds didn't play, restarting my PC fixed the matter.

The sounds don't play in my game. Any clue ?

Yes, I agree. The chanting on spell casting, the volume on that needs to be brought up by atleast 50%.

Awesome, but the sounds are really soft.

That is indeed a LOT of files, and the amount of work you've put into this is insane. Kudos!

Now. The files that deal exclusively with the "chanting" are the final 20 in the list. They all start with "vs_chant" in the name. For my own personal use, I went ahead and amplified their volume by 10dB. This came out much better in my opinion, and there's no noticeable clipping.

I don't know how to redistribute Workshop mods myself, nor would I want to since this is yours and I would never want to take your well-deserved credit for it. That being said, I would be happy to email these 20 sound files to you if you would like to have them for your mod or if you want them as an alternate version. I know you already put a ton of work into this, and this way you wouldn't have to bother with doing anything extra. Just let me know if you'd like to have them.

Okay. I've deleted all my previous ramblings so that I don't spam your workshop page, and I'll just summarize with this.

First of all, FANTASTIC work! This is exactly what I've been looking for in NWN, and you've done a terrific job.

I do agree with previous posters however that the chanting is too quiet compared to the rest of the game's sound effects. SO. I took the liberty of finding your mod files myself. They are located here:
C:\Program Files (x86)\Steam\steamapps\workshop\content\704450\1873336610\override

Awesome work! Spells incantations was the one element in original release that was missing. I know there was a patch later on which adds spellcasting voices, but those were never as good as in Infinity Engine games. Is it normal that Enhanced Edition of NWN doesn't have any incantations or is it some kind of bug due to playing with polish dubbing?

Tried it out, not my thing, but works 100% as intended!
