Where do you find the TM hypnosis in Pokemon white 2?
There is no TM for Hypnosis.
You can't, there is no such thing as a Hypnosis TM. Your Pokemon must be able to learn it, like gastly, which u can catch frequently at the lost tower What sucks about that is that you can't trach Hypnosis to a Pokemon because there is no TM for it. The Pokemon has to learn it by leveling up. There might be some Move Tutors who might be able to teach such a move, but…
There is no TM you can get that makes Pokemon fall asleep, there is hypnosis, which u can not get as a TM, only certain Pokemon can learn it at a certain level, and there is dark void, and i believe only 1 Pokemon can learn that move and that's darkrai. theres also grasswhistle, obviously only grass Pokemon can learn it but that is also not a TM move. certain Pokemon randomly learn it.
