Corruptions

Source Starfinder #10: The Diaspora Strain pg. 41
Corruption is an insidious affliction of the soul. A number of different corruptions exist, from the mind-rending horror of ghostly possession to the monstrous physical transformation of lycanthropy. However, all corruptions function in a similar way. When a character first contracts a corruption, it shows itself in minor symptoms—brief bouts of melancholy or a mild fixation on unusual stimuli or a particular environment. The corruption eats away at the victim’s mind and spirit with the promise of dark gifts that come with frightful drawbacks. Fighting these temptations is draining on a victim, and some spend their entire lives on the verge of giving in. Others believe they can control their corruption, and allow the corruption to progress in order to gain the power it grants. Such beings eventually become completely defiled as corruption takes a permanent hold over them.

Fiendblood Corruption

Source Mechageddon! pg. 170
Mortals who consume fiendish tissue or embed it into their bodies (for example, through magical limb grafts, organ transplants, or blood transfusions) are exposed to fiendblood corruption. Fiendblood corruption is an affliction with the following parameters.

Fiendblood Corruption

Type physical corruption; Save Fortitude DC = 10 + half the victim’s level + the number of manifestations the victim has; on a failure, a victim can spend a number of Resolve Points equal to 1 + the number of manifestations the victim has to succeed instead.
Frequency 1/day
Cure Destroy the fiend that donated the tissue, or the victim can purify themselves by spending 1 month receiving blood transfusions from a compatible nonfiendish creature, surgically removing fiendish growths, or bathing in holy water. At the end of each month spent this way, the victim can refuse a previously accepted gift, allowing break enchantment or remove affliction to remove the related manifestation. Using a gift from any corruption while undergoing purification means the victim has to start that month over.

Description

Like all corruptions, the fiendblood corruption begins with subtle signs—intrusive thoughts, strange cravings, and troubling but minor physical changes, such as fast-growing nails, oddly hued eye specks or strands of hair, or shifting patches of discolored skin. Over time, the corruption grows until the victim can’t deny the changes they’re experiencing. Eventually, a choice of whether to embrace the corruption and its gifts or resist and remain fully mortal without stain must be made. Which will you choose?

Fiendblood Progression

When you gain your first manifestation, your body begins to transform. At least one minor change of your choice occurs with your body, such as small horns, altered sclera, or elongated teeth.

When you gain your second and third manifestations, your body changes drastically. An additional major change of your choice occurs, such as becoming substantially taller, growing a tail or wings, or your blood changing color.

Once you accept your fourth gift, changes to your body intensify. You’re no longer quite mortal, though you haven’t yet fully transformed into a fiend. Your appearance morphs to look more like that of the demon where your fused parts came from. If you accept a fifth gift, you transform completely. You are now a fiend. You become chaotic evil if you aren’t already, and your creature type changes to outsider with the chaotic, demon, and evil subtypes.
