It is about *hunting* a muter. Which you can't do in any reasonable capacity that I'm aware of. I believe I had an archer cave ranger briefly during Jahku's time that could see him in caves and see him in chamo, so in theory he could be hunted, but in practice even that character didn't see Jahku 90+% of the time and couldn't track him reasonably because duo works everywhere... Also I couldn't attack him directly even when I could see him... Just eat violet roots and hope.
