Magical Bond

The bond between you and your companion transcends material limits, and takes on a magical strength. 

• Increase your Wisdom or Charisma score by 1, to a maximum of 20. 
• You learn the find familiar spell if you don't already know it. 
• Instead of choosing a creature from the find familiar spell's list, you can instead choose a willing companion whose Bond Strength with you is 12 or higher. The creature retains the statistics, type, and appearance it had before the spell was cast. If you cast the spell on another creature, or change its form, the companion instead loses the benefits from the spell. If it is in a demiplane when you do this, it appears in an unoccupied within 30 feet of you. 
• Your familiar's maximum hit points are increased by a number equal to your caster level.
