Tunnel Entrance: Demons take a shortcut through the tunnels to a different part of the map. During setup before shuffling tiles, replace two of the Mountain tiles with the two Tunnel tiles (entrance and exit). After creating the map, place one rotation token on the tunnel entrance and another on the exit. 'Rotating' the entrances causes the exist and entrance cards to switch places. This is a Mountain tile only for the purposes of Scroll placement.
Tunnel Exit: Any Demon that lands on the Tunnel Entrance tile travels to this tile on their next movement. It is very difficult to capture demons while they are entering and existing the tunnels. Obelisks receive a strength penalty of -3. (A strength 4+ Obelisk can capture strength 1 Demon in the Tunnels.) See Tunnel Entrance tile for setup instructions. This is a Mountain tile only for the purposes of scroll placement.
