Didn't he just use the bloodlust spell on him? The one he got way back when he first killed that hunter squad that trapped him in the spider boss room. If I recall correct it makes some1 imbued with fear and unable to move for 1 min.
the novel is more detail compared to manga. based on novel, Jinwoo got angry and he released his attact with killing intent. that intent suffocate Goto, make him felt almost dead. these strongest hunters manage to detect it and jump to stop him in time (while the weaker didn't know what had happened). but they all can't detect his shadows.
