Improved Familiar

Your understanding of the Find Familiar spell results in a more powerful familiar. Your familiar gains the following benefits:

• Its number of hit dice double.
• Its proficiency bonus increases by one.
• It receives an Ability Score Improvement
• When you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one attack of its own with its reaction. If it already has this ability, it can instead take the Attack action on its own turn.
