Installation:
1. Download the mod folder.

2. Go to your Pathfinder directory and access the Windows folder at Kingmaker_Data\StreamingAssets\Audio\GeneratedSoundBanks\Windows. (If you use a Macdonalds then go to the Mac folder in GeneratedSoundBanks instead.)

3. Open the mod folder and and drag its contents ("main.bnk" and "CRE_Mastodon.bnk") into the Windows folder, replacing the original soundbanks (which you should create backups for).

4. Done!
