Eye of the shadows

Level 1: Eye of Control: You have the ability to control any birds that are bellow 30in tall. You can hear anything the bird hears and can see what it sees with your right eye. Your right eye must remain open, or the connection will be cut off. Every turn, you have to make a con check and it has to be above a 10 at the start, and the DM can rise the number depending on the situation. (The range of the connection only lasts 60 ft.)

Level 5: Dark Warrior: A black smoke emits around you forming the shape of armor, and you gain a temporary +2 to your AC, and it can grow by +1 when you reach 5th, 10th, 15th, and 20th. (There is no concentration needed, the armor just only lasts for 2 hours, and can be called off at any time.)

Level 8: Eye of Illusions: A smoke form around you then turning you into anything that isn't above 7 ft tall. (It can be an image like a plant burning, with the sounds of the cinders included with the fire illusion.) (Casting range is 15ft and can last up to 10 minutes.)

Level 12: Eye of Chaos: 1-4 tentacles emerge from the ground at your will and can grapple or hit anything. (When hitting something, roll 4 D4s.) (Casting range is 30Ft)

Level 15: Last stand: If you are at anything between 1-10 hit points, you can cast this, which forms black smoke around your body, turning yourself into a krow beast-like creature. (You gain 10 temporary hit points, your attacks have advantage, and every attack you do gets a 1d10 of damage.

Level 20: The Showstopper: Your eyes turn black, and gravity shifts around you making anything that is under 220 lbs levitate. You can now do any of your attacks x2 for the remaining of 2 hours you character has left before your character dies.
