Continuing with the Revalian Nights arc, this map is a climbing and espionage map for players to gain access to the inner city. Players need to get into the sewer system to access the city, but the very thickmetal gate bars the way. To get around this players climb the wall using foothold items randomly placed. The foothold image I used is below:
To make things more difficult, there are two devices in the control room. One lowers and raises the gate (I had this be the green button), while the other detects and suppresses magic and supernatural abilities. This forced my players to go up the wall the old fashion way, with numerous climb and leap checks as some of the bricks came loose under them. Once to the top of the wall, they had to take out the patrol wandering above the gate.
