Each episode has 15 Discovery cards. These include Items, Companions, and Conditions that can help or hinder you. Most Discovery cards can be claimed by fulfilling the requirements listed on the card’s central section. Investigators claim either the left or right side of the card, tucking them under their investigator board on the appropriate side. If it’s not specified when the investigator may use an effect from a Discovery card, it may be used anytime during their turn. However, it cannot be used while resolving another card, effect, or during a roll.
