To resolve an encounter, apply the effect on your chosen card, spending and gaining resources as indicated. Spending and gaining resources in this manner is known as the encounter effect. If you do not have the resources listed in the Spend Field you cannot choose to resolve the encounter.
You can choose a card even if your time will go under zero with your Time tracker.
You will receive the full benefit of the card you used during Exploration but will be ambushed immediately after.
