Greater Magical Bond

Adventurers who spend enough time with their familiars as companions find certain loopholes in the find familiar spell’s function, allowing their companion even greater strength. You gain the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• Your familiar can take the attack action on its turn.
• You can dismiss or summon your familiar as a bonus action.

Note: Dnd Beyond lacks the "Choose Intelligence, Wisdom, or Charisma" option as a modifier subtype to bonus so please ignore the Dex option and pick one of the other 3.
