This is one of the better horror healing cards at level 0, provided you have the hand slot available. Agnes Baker especially likes it since each horror healed potentially translates into an extra damage to an enemy. A fully spent Grimm’s Fairy Tales combined with Forbidden Knowledge gives +2 resources and 4 direct damage for 2 cards and 2 actions— not bad!
Uses (4 secrets).
After an investigator at your location fails a skill test by 2 or more, exhaust Grimm's Fairy Tales and spend 1 secret: Heal 1 horror from that investigator.
