Eldritch Invocation: The Chain Unshackled

Prerequisite: Level 9+ Warlock, Pact of the Chain Invocation

You learn the Find Greater Familiar spell and can cast it as a Magic action without expending a spell slot.

In addition, any familiar summoned via that spell possesses the following enhancements:

The familiar gains a bonus to its AC, attack rolls and saving throws equal to your proficiency bonus, and it adds your Charisma modifier (minimum of +1) to the damage of its attacks.

In addition, the familiar’s hit point maximum increases by an amount equal to your warlock level, and it uses your proficiency bonus in place of its own for any abilities that reference its proficiency bonus.

You may use your bonus action to allow your familiar an additional action on each of its turns. That action can be used to take only the Attack (one attack only), Dash, Disengage, Hide, or Utilize action.

Finally, whenever you cast a warlock spell on your turn, you can cast it as if you were in the familiar’s space, instead of your own, using its senses.
