Apologies if these have already been answered, there are just so many threads to read now and didn't get lucky with search.
1. If a Hero dies, do you loose all associated resource tokens?
2. How do you use cards with an X cost on them? E.g. Stand and Fight (spirit)says "choose an ally with a printed cost of X..." Is X the number of resource token you're willing to spend upon using that event?
If you choose an ally with a printed cost of 3 for example, you will have to spend 3 resources. The cost to play the event card is the cost of the chosen ally card.
