Ball of Shadow

This is a ball made up of pure shadow. You can manipulate the shadows to do the following things:

1. Give you a Burrowing, Climbing, or Flying speed of 100 feet.
2. Give you an armor class of 20.
3. Make 20 shadow spears that do 1d10 cold, necrotic, and force damage each.

You can also make the ball self destruct which will give you an immunity to all damage types for 1 turn.
