Split Familiar

With significant knowledge of the Find Familiar spell, you have learned how to split it into two creatures. When you cast Find Familiar and have a familiar which is at 1/4 level or bellow and is at size tiny or smaller, you may summon another familiar which is at 1/4 level or below and is at size tiny or smaller. Both familiars must be of the same creature type. When you choose to perceive through your familiar's senses or command it to attack (as with Enhanced Familiar), you may only choose one familiar within range. Using an action, you may reduce the hit points of one of your familiars by any amount. That amount of hit points is given to your other familiar as temporary hit points for 1 hour.
