Carolyn Fern, a new character playable from Forbidden Alchemy, has a Once Per Game mental card called Hypnosis that she may select at the beginning of the game. It says, "Once per game, you may take any number of horror (without exceeding your Sanity). For each horror you take, choose an investigator in your room to heal 4 horror." The way this is stated, it may include herself. That's not the problem.
The real treat of Carolyn Fern is her card should practically say, "Once per game, heal all horror from each investigator in your room (including yourself)." Because the actual card text states no maximum use for healing investigators in her room, she may continue to incur 1 horror on herself to heal 4 horror on a chosen investigator, including herself. So long as you do not exceed her max sanity, you heal all investigators in the room.
I assume the Hypnosis card meant to say along the lines that each investigator in the room may only be targeted once, respectively, but what do you guys think?
