How can I climb up a hole?
To climb up a hole you must have a rope. You can recognise holes in the ceiling by noticeable spots on the floor. Simply use the rope on the field of such a spot and your character will climb up through the hole. Please note that this will even work if anything else is on the rope spot or if you are standing directly on it. If you are standing next to a hole in the floor, you can use a rope to pull up other characters, objects and even creatures from below.
