Faithful Familiar

You learn the Find Familiar spell. It doesn't count toward the maximum spells you know or prepare and you can cast it as a ritual. When you cast that spell, the familiar is a beast instead of a celestial a fey or a fiend, and its hit points maximum increases by an amount equal to twice your ranger level. 

In addition, when you hit a target that is within 5 feet of your familiar for the first time on your turn, your attack deals an extra 1d4 damage.

This feature's extra damage increases when you reach certain levels in this class: to 1d6 at 6th level and to 1d8 at 14th level.
