Arcane Wall

You create a wall of pure Arcane energy that is up to 10ft by 10 ft in any one direction. You can also shape the arcane energy into a shape, like a box, sphere, or dome. When doing so, reduce its size in half (a 5 foot cube for example). The wall has Health equal to X times 3 and Toughness equal to X times 2. For each additional Stamina you spend, you can add another wall connected to the first that is up to 10 x 10.
