Monks of the Mutant join a tradition cloaked in secrecy and scorn, for most other monks shun the process by which these monks pursue bodily might. To follow the Way of the Mutant, a monk must mutate their own blood to manipulate their ki. The result transforms the monk at the most fundamental level, but to do so reaps reward that the body could not normally provide.

Bonus Proficiencies

When you choose this tradition at 3rd level, you gain proficiency in the Medicine skill if you don’t already have it. You also gain proficiency with your choice of Alchemist's Supplies, Brewer's Supplies, or the Poisoner's Kit if you don’t already have it.

Blood Mutagens

At 3rd level, you learn two mutagens of your choice from the Mutagen List. You can take one minute to concoct a single mutagen, which must be consumed within 24 hours or it loses its effect. Consuming a 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 and cannot be consumed by others.

You gain access to one additional Mutagen at 6th, 11th, and 17th level. Additionally, when you gain access to an additional mutagen, you may replace a mutagen you already know with another.
