Create Hojunkulus

While speaking an intricate incantation, you carefully cut yourself with a jewel-encrusted dagger worth 200 gp, taking 2d4 piercing damage that cannot be reduced in any way. You then let your blood drip onto the spell’s other components and touch them, transforming them into a unique construct known as a Hojunkulus.

The statistics of the Hojunkulus are similar to those of a standard homunculus, with a few key differences. The Hojunkulus is your faithful, albeit flawed, companion, bound to your life force. It dies if you die.

Whenever you finish a long rest, if the Hojunkulus is on the same plane of existence as you, you can choose to transfer some of your life force to it. To do this, you can spend up to half of your Hit Dice. For each Hit Die you spend, roll the die and add your Constitution modifier to the result. The total amount rolled is subtracted from your hit point maximum and added to the Hojunkulus’s hit point maximum and current hit points. This transfer can’t reduce your hit point maximum below 1, and the changes to your and the Hojunkulus’s hit points last until you finish your next long rest. Your hit point maximum can’t be restored by any means before then, except if the Hojunkulus dies.

You may only have one Hojunkulus at a time. If you cast this spell while your current Hojunkulus lives, the spell fails.
