Whenever you roll a 1 during a test as part of a Combat Encounter, you may reroll that die.
The cavern you find yourself in widens as you venture deeper, coming at last to a great hall. Granite archways lead you along a cobbled path to a stone temple, at the center of which swirls a massive pillar of flame.
Beyond the fourth archway, two bearded priests stand waiting. They warn you of the dangers beyond the cavern, but gives you their blessing in the form of a tarot card, insisting that it will protect you from harm. You thank them and continue on your way.
