These enemies attack you in psychic combat, using craft.
• If you kill a spirit, keep that card as a trophy to exchange for a craft counter. To exchange a trophy (or multiple), the total craft of the enemy card(s) must meet or exceed your current craft (including craft counters but excluding points from cards). If your craft was 4, you could exchange one ghost (craft 4) to receive one craft counter.
• If you do not defeat the enemy, leave that card on that space.
