He will work, but once a KO click is revealed on Eclipso's dial (clicks 10-12), he is removed from the game (Eclipso). So once you get past Joker's first half of his dial, it starts to look scary...

According to that judge's post, a possessor would only be ko'ed if haha joker stops on a ko click, so if you take damage and go past clicks 10-12 and land on 1 or something again, then the possessor is not ko'ed.

@maraxusofk you are correct. That was what I intended to say, forgetting that reveal has its own meaning when turning the dial. If you can ensure you get hit past his KO clicks then the possession stays. If you land on a KO click, he's gone.

What if i use an entity in werewolf by night?
