Explore
This action is only available during delves. When you perform this action, you count the distance to an explorable hex in The fallback content to display on prerendering. If it is equal to or less than your The fallback content to display on prerendering, you trigger an exploration on that hex.
The explore action is once per turn. You cannot perform an explore action if you have already performed a move action that The fallback content to display on prerendering; you also cannot perform a move action if you have performed an explore action.
The explore action and exploration are related concepts but are not identical terms. The explore action triggers an exploration, but exploration can also be triggered in other ways, such as moving into a hex.
