Player invisibility and see invisibility virtually doesn't work anymore as of patch 6. If you want to stop them from going invisible, inflicting the wet condition gives enemies the same bug permanently attached to myself. If you have someone who can cast an upscaled create water, that might work. Knocks them out of it with no safe and -- seemingly -- removes the option from the board for 3 turns. Storm Sorcerer is a pretty good class in patch 6.
