Path of the Married Man

Your family cheers you on from within as you splatter the blood of the unworthy on your fingers, one laden with the ring of the covenant that not even til death will you and your wife part. And for as long as you all shall persist, death is an option your wife is not affording to you; though she is always with you, never will you feel her embrace again, until your work on earth is done.

Raging Trinity

3rd Level: Inside of you are not one, but three; you are no longer in control of your limbs. You control what you think and say, your wife controls your left leg and hand, and your daughter controls your right leg and hand. While they generally listen to you, at times they will know better than you what to do with your extremities. Once per long rest, you can choose to briefly disassociate during rage, and let your ghostly family take the wheel. This causes you to deal an extra 2d4 in either cold or radiant damage for 3 turns, thematically depending on whether you say your daughter or wife is controlling you, respectively. However, you are not so nimble as when you control yourself, and during this period you have disadvantage on dexterity rolls and saving throws. The damage increases by 1d4 every other level past this one.

Three Heads Are Better Than One

6th Level: Your wife and child have spent enough time in your body to see what you see, and hear what you hear. They can remind you of things you've seen and heard, even if you don't remember. You know what cardinal direction you're facing at all times and what time it is, and once per long rest, they detect a weak spot in an enemy's defense, giving you a guaranteed hit if you miss an attack roll.

We Are Your Shield

10th Level: Your family confers their vitality to you, that you might finish your earthly efforts. You get a +4 to AC if you have no shield equipped while raging, and you now have resistance against all damage types while raging, magical and nonmagical. In addition, when you are asleep or unconscious, you can speak to them, though they won't know anything about any afterlife, as they've foregone it to reside in you.

Your Work Is Not Finished

14th Level: When you reach 0 hitpoints or lower, as long as you are not killed outright, your family assumes complete control over your body if you were raging during that time. You get half your total HP in temporary HP. Your rage continues, and their voices speak through your lips and they deal all damage as either radiant or cold, as you choose. When your temporary HP runs out, your character must roll one death saving throw, and this success or failure determines your fate if you aren't stabilized or healed.
