Biomancy: Miasmism Magic

Some consider biomancy unnatural, but it’s the biomancers of Tanmaa who are responsible for many of the hybrid and augmented creatures who fill the Western Division of Caphora, and while biomancers have been blamed for some of the plagues that have struck the continent, they’re the first to be called when plague strikes to control it.

Most biomancers are found in the labs of Tanmaa, but some nobles hire them as extremely expensive personal physicians. Some biomancers are the products of their own labs who have learned, through observation and sometimes deliberate training, to use the very magic that created them.

Biomancers specialize in one of four forms of the craft. They can use other biomancy spells but prefer their own tradition.

Other Campaign Worlds
While the Biomancer was developed specifically for the Caphora campaign world, it will work with most existing campaign worlds, especially those with a slight “mad science” or steampunk element, gnomes who like to tinker, or campaign worlds with hybrid creatures or characters.

The caster has learned to manipulate miasma, invisible traces in the elements that corrupt their nature and cause disease and decay.

Free Breathing

With a bonus action, you can touch a willing creature, giving it the ability to breathe underwater and resistance to all gas-based poison and disease attacks for 1 minute or until the caster cancels the effect.

After using this feature, the caster must complete a long rest before using it again.

Purge Miasma

With an action, you can purge all traces of miasma in a 30 foot radius, curing all disease and neutralizing all poison within that radius. This affects those suffering from these effects but does not reverse the effects or damage already sustained, nor does it grant immunity to future infections. It also affects creatures that carry infectious disease, neutralizing their ability to spread it further.

After using this feature, the caster must complete a long rest before using it again.

Conjure Miasma

With an action, you can conjure a fog of miasma, which causes disease to all within a 10 foot radius of the caster as if affected by the Contagion spell (Constitution saving throw applies). The caster is immune to their own effect.

After using this feature, the caster must complete a long rest before using it again.

Miasmatic Immunity

You have spent so much time manipulating miasma that you’ve become immune to disease, resistant to poison, and resistant to any spore-based attack.
