Hunters who wear it´s equipment are either possessed, turned into a Fatalis themselves, killed or simply disappear (none of which sound pleasant) and Smithies who make said equipment suffer misfortunes. I know MH tries to explain, on a "reasonable" way, the monsters and their abilities, but for Fatalis there can´t be any other explanation other than "a completely evil Eldritch Abomination out for the human race".
