ok i don't understand the hunting horn
if i attack with X X (two white notes) and then press R, I play something that gives me attack deflection bonus. If I try some of the other combos listed online (e.g white red) then press R, nothing happens.
I have that primo Zurogong if that is relevant (it can play white(X)/red(A)/yellow(X+A)
Different horns, different buffs.
