Monks of the Way of the Unending Death are obsessed with the meaning and mechanics of dying.They capture creatures and prepare elaborate experiments to capture, record, and understand the moments of their demise. They then use this knowledge to find a way to stop the cycle of life and death.

 

Touch of Death

Starting when you choose this tradition at 3rd level, your study of death allows you to extract vitality from another creature as it nears its demise. When you reduce a creature within 5 feet of you to 0 hit points, you gain temporary hit points equal to your Wisdom modifier + your monk level (minimum of 1 temporary hit point).

Undead Thralls

At 6th level, you gain the animate dead spell as a ritual magic.

Undying Nature

Beginning at 10th level, you can hold your breath indefinitely, and you don’t require food, water, or sleep, although you still require rest to reduce exhaustion and still benefit from finishing short and long rests.

In addition, you age at a slower rate. For every 10 years that pass, your body ages only 1 year, and you are immune to being magically aged.

Touch of the Long Death

Starting at 17th level, your touch can channel the energy of death into a creature. As an action, you touch one creature within 5 feet of you, and you expend 1 to 10 ki points. The target must make a Constitution saving throw, and it takes 2d10 necrotic damage per ki point spent on a failed save, or half as much damage on a successful one.
