Dincuff's Spirit Familiar

You manifest a portion of your life energy as a familiar, a spirit that has the same effects as the Find Familiar spell. In addition, it has the following traits: 

• It is a celestial instead of a beast.
• In combat, it takes its turn immediately after yours.
• Whenever you regain hit points while your familiar is within 10ft of you, treat any dice rolled to determine the hit points you regain as having rolled their maximum value for you. The distance rises to 30ft at 5th level; 50ft at 11th level; and 75ft at 17th level.
• When the familiar drops to 0 hit points, it disappears, leaving behind no physical form. Additionally, when this occurs, you take 1d4 force damage as the backlash of momentarily losing part of your soul takes its toll. This damage rises to 2d4 at 5th level; 3d4 at 11th level; and 4d4 at 17th level. You cannot resist or be immune to this damage in any way.
