I think it's all the same , it just gives you different dialogues .
You can try :
Nyx
Kanathar
Cray
Torgar does nothing i tried
oka, thanke!
I honestly tried to use the minotaur's own name for it, surprised that didnt work haha; seemed the most logical
It is the minotaur's name though, Tiadane
it didnt work for me
