Hua Thief

An ancient script practice rejected by most monasteries for its forbidden practice of stealing ki energy or Hua from another life force. Such practice is viewed upon as vampirism and worse by even most the darkest monks. Once you become a master at controlling and stealing Hua, your body become timeless and ceases to age

Hua Drain

Hua Purge

At Level 6, when a creature fails the save for Hua Drain you gain an extra benefit. The creature takes your Wisdom modifier in necrotic damage, and you receive double you Wisdom modifier in temporary Hp.

Trance

At level 11, you don’t need to sleep. Instead, you meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that you would from 8 hours of sleep.

Hua Hunger

At level 11, when a creature fails a save against your Hua Drain, instead of gaining the normal benefits you can choose to paralyze the creature instead. Doing this takes one 1 year off the creature life and adds it to your own instead. The paralyzed creature can repeat the Dc save to end the condition at the end of its turn.

You may only use this feature once per long rest. 

Hua Master

At level 17, when a creature fails your Hua Drain, you can choose to instead of gaining the usual benefits you can drain their entire life force. This will instantly destroy any creature with a CR rating at or below level 4. Absorbing this will boosts your Hua flow, for 1 minute you are resistance to all damage except for psychic and radiant, and you have advantage on your first attack once per turn.

You can use this feature twice every long rest.
