If a model that is HT 2 and has Mv 4, chooses to use the (2) Jump action from a piece of terrain that is HT 2 and is at the edge of it, but there is a fence or small wall (Terraclips thick) around the edges of the terrain that are HT 1. How many inches does the model fall, and would it make a damage flip, please explain in detail why. Also, if the model is pushed in a manner similar to the scenario above. What happens to it? Thanks in advance.
