Order of the Undying Mutant

Who says that there is an end for us all? The Order of the Undying Mutant does not believe that there has to be an end to life. Inspired by the undying nature found among certain creatures they hunt, the order strives to make the creatures' everlasting life their own. By relentlessly studying their foes and using their studies to experiment with various homebrewn alchemical concoctions, the few hunters in the order have gained powers similar to the undying creatures they hunt.

 

Formulas

You begin to uncover forbidden alchemical formulas that temporarily alter your mental and physical abilities.

Beginning at 3rd level, you choose to learn three mutagen formulas. Your formula options are detailed at the end of this order description. You gain an additional formula at 7th level, 11th level, 15th level, and 18th level.

Additionally, when you gain a new mutagen formula, you can choose one of the formulas you already know and replace it with another mutagen formula.

Mutagen Craft

At 3rd level, you can take a short rest to concoct a single mutagen. Consuming a single mutagen requires a bonus action, and the effects (including side effects) last until you complete a short or long rest, or spend an action to focus and flush the toxins from your system.

Mutagens are designed for your biology. They have no effect on large or larger creatures, and only impart the side effects on other medium or smaller creatures that drink the entire mutagen. They are also unstable by nature, losing their potency over time and becoming inert if not swallowed before you finish your next short or long rest.

Your body will begin to better utilize the toxins you instill it with as you grow in power and experience. These advancing mutations may be signified by a Mutation score.

Mutation Score = your blood hunter level divided by 4, rounded up.

Defy Death

Starting at 7th level, your obsession with life and death has taught you the spare the dying cantrip.

Additionally, you can give yourself vitality when you cheat death or when you help someone else cheat it. You can regain hit points equal to 1d8 + your Constitution modifier (minimum of 1 hit point) when you succeed on a death saving throw or when you stabilize a creature with spare the dying.

Once you use this feature, you can’t use it again until you finish a long rest.

Embracing Life

At 7th level, your attachment to life has taught you how to make the most of your slain enemies. Whenever you reduce a hostile creature to 0 hit points with a weapon attack, and kill it, you regain hit points equal to your crimson rite damage die.

Additionally, your body has begun to adapt to toxins and venoms, ignoring their corroding effects. You gain immunity to poison damage and the poisoned condition.

Undying Nature

Beginning at 11th 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.

Indestructible Life

When you reach 15th level, you partake of some of the true secrets of the Undying. On your turn, you can use a bonus action to regain hit points equal to 1d8 + your blood hunter level. Additionally, if you put a severed body part of yours back in place when you use this feature, the part reattaches.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Exalted Mutation

At 18th level, your body has begun producing one of your toxins naturally. Choose one of your known mutagen formulas. You gain the benefits and side effects of this mutagen permanently, at all times. You cannot change this choice of formula after this feature is acquired.
