Air Bending

You choose water that you can see within range and that fits within a 10-foot cube. You affect it in one of the following ways:

• You instantaneously expand the air 10 feet in one direction
• You instantaneously drain the water within the cube.
• You double or halve the power of the air, change its density or change its colour, or both. The change lasts for 1 hour.
• You cause simple shapes—such as the vague form of a creature, an inanimate object, or a location—to appear as air and animate as you like. The shapes or form last for 1 hour.
• This form if made correctly can cause damage, damage table below.

If you cast this spell multiple times, you can have up to three of its non-instantaneous effects active at a time, and you can dismiss such an effect as an action
