Soul Torn Familiar

You gain the find familiar spell and can ritually cast it with half the cost and some blood (taking 1 point of damage).  The rules of the spell apply, except their is no limitations on connecting with the familiar  but the available familiar options open to the warlock pact of the chain subclasses options. However, when the familiar is killed or harmed you take damage equal to double the creatures (as if it was an enemy) hit points. Your familiar no longer counts as a celestial fend or fay it reflect the caster for all tracking  and detecting purposes.
