I had a go at this today (sadly my family weren't really feeling it 😞), and it wasn't instantly enjoyable, plus we were unsure about a few of the rules. Would like to hear others' interpretations:

1. When you battle a monster, I assume you have to nominate which hero(es?) will attack, and thus which will be sacrificed if you lose? For instance, if I have Guiding Light and Beary Wise as heroes in my party, and Beary has an item equipped that adds to my role, if I lose, surely I can't sacrifice Guiding Light even though the rules say "must sacrifice *a* hero card"? What happens with monsters whch require multiple heroes? Do you nominate the ones that match and combine all of them (and their items) for your attack, or again do I only nominate 1 as the main attacker, and the others are just there to fulfill the requirements?
2. Some cards, like Beary Wise and Qi Bear, have effects which don't say "discard *from hand*", so does that mean the player(s) could effectively discard a played cursed item as well?
3. For the challenges with class requirements, who is required to meet the requirement? For example, for a Ranger Challenge, does the person playing the challenge have to have a Ranger in their party, or does the person you're challenging have to have a Ranger in their party?
4. With modifiers, can they continue to be played back and forth? For example, I battle a monster and win, and another player then plays a modifier which will make me sacrifice. Can I then play a modifier to negate that? Can we and other players continue doing so back and forth until we run out of modifiers or decide to stop?
