The process of the Hunter’s Bane is a painful, scarring, and sometimes fatal experience. Those that survive find themselves irrevocably changed, enhanced. Some found this experience exalting, embracing the ability to alter one’s own physiology through a combination of hemocraft and corrupted alchemy. Over generations of experimentation, a splinter order of blood hunters began to emerge, one that focused on brewing toxic elixirs to modify their capabilities in battle, altering their blood and, over time, become something beyond what they once were. They called themselves the Order of the Mutant. Researching their targets to know their strengths and weaknesses, these blood hunters can alter their biology to be best prepared for the coming conflict.

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

Beginning at 3rd level, you choose to learn four Mutagen formulas. 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 a new mutagen formula.


At 3rd level, you can concoct a single mutagen when you finish a short or long rest. Starting at 7th level, the number of mutagens you can create when you finish a rest increases to two, and you can create three mutagens at 15th level.

As a bonus action you can consume a single mutagen, and the effects and side effects last until you finish a short or long rest, unless otherwise specified. While one or more mutagens are affecting you, you can use an action to focus and flush the toxins from your system, ending the effects and side effects of all mutagens.

Mutagens are designed for your biology and have no effect on other creatures. They are also unstable by nature, losing their potency over time and becoming inert if not used before you finish your next short or long rest.

Strange Metabolism

Beginning at 7th level, your body has begun to adapt to toxins and venoms, ignoring their corroding effects. You gain immunity to poison damage and the poisoned condition.

In addition, you can instill a burst of adrenaline to temporarily resist the negative effects of a mutagen. As a bonus action, you can choose to ignore the side effect of a mutagen affecting you for 1 minute.

Once you use this feature to resist side effects, you can’t do so again until you finish a long rest.

Brand of Axiom

At 11th level, your hemocraft has altered your Brand of Castigation to enforce a foe’s true nature. Any illusions disguising or making a creature invisible when you brand them end, and they can’t benefit from such illusions while branded. If a creature branded by you is polymorphed or has changed shape, they must succeed on a Wisdom saving throw or revert to their true form and be stunned until the end of your next turn. Whenever a branded creature attempts to polymorph or change shape, they must succeed on a Wisdom saving throw or the attempt fails, and they are stunned until the end of your next turn.

Blood Curse of Corrosion

Starting at 15th level, your blood curse can wrack a creature’s body with terrible toxins. You gain the Blood Curse of Corrosion for your Blood Maledict feature. This does not count against your number of blood curses known.

Exalted Mutation

At 18th level, your body has adapted to produce your toxins naturally in a moment of need. As a bonus action, you can choose one mutagen currently affecting you to flush from your system and end, then immediately have a mutagen you know the formula for take effect in its place.

You can use this feature a number of times equal to your Intelligence modifier (minimum of 1). You regain all uses of this feature after you finish a long rest.
