You're forgetting that Jaune actually managed to land an attack on the Nuckelavee, and all it did was make the Nuckelavee kick him. There's also the fight that Ruby had with a Beringel in the Volume 4 Character Short where her slashes did absolutely nothing until the very end of the fight. Grimm can have tough skin.

And what I was saying was: Even if the Grimm can't see him, they could still hear him and would feel it when he attacks them or jumps onto them, which would alert them to his presence and approximate location.
