1. What is still unclear after the official answer?
Q: "There are three treasures that offer one-time healing to a hero: Jinn's Lamp, Amulet of Healing, and Crystal of Tival. All three say "Discard after equipping at the start of your turn..."... Should "at the start of your turn" just be ignored, or does it have some other significance?"
A: It can only be used at the start of your turn after Step 2: Equip Items. The result is that you will have only 1 Other item (if any) equipped.
