During a delve, adventurers explore the battle map by interacting with the hexes of the map. When an adventurer explores a hex, they draw a delve card and reveal a new tile to connect to the map. As tiles are connected, the map expands, and additional connection hexes open up to explore.

An adventurer can trigger an exploration of a hex in 2 ways:

• Occupying an Explorable Hex: During their turn, an adventurer may choose to trigger an exploration when they move into or are placed in an explorable hex, or when they start their turn in that hex. The adventurer can continue a move action that was interrupted by this exploration. Exploring in this way is not considered to be an explore action. Note that companion units cannot explore hexes.

• Performing an Explore Action: An adventurer can also trigger an exploration by performing an explore action targeting an explorable hex. To perform this action, choose an explorable hex in sight and measure the distance to that hex. If it is within the adventurer’s movement range (based on Stamina), an exploration of that hex is triggered.
