This tiny mod silences the audio played by the vendor NPCs that appear on these mounts:
- Mighty Caravan Brutosaur (Collector Unta and Merchant Maku)
- Grand Expedition Yak (Mystic Birdhat and Cousin Slowhands)
- Traveler's Tundra Mammoth (Hakmud of Argus, Mojodishu, and Drix Blackwrench)
Other NPCs who have the same welcome and goodbye lines will also be muted, because it's the sound file itself that's prevented from playing.
There is no in-game configuration, display, or chat messages. Just install it and it's done.
