Disease can become a corruption when it causes long-lasting and physical changes to the body.
Suffering a magical disease for a prolonged period can induce the plagued corruption.
You carry the symptoms and appearance of one suffering from a disease, even if you’ve been cured of the illness that triggered your corruption or are otherwise normally immune to disease. Further, once you gain the plagued corruption, you lose any immunity to disease and cannot gain such immunity from magical spells or items or other effects. Only living creatures can gain this corruption.
Once per month, if you did not infect a number of creatures equal to or greater than your manifestation level with a disease you are carrying, you must attempt a Fortitude saving throw（難易度 ＝ 15 ＋ your manifestation level）. If you fail, the next time you rest, you immediately gain a new disease of the GM’s choosing（without a further saving throw） and black out, losing control to the insidious delirium of the disease. You must seek out and infect any creature you can find before the next sunrise. If you succeed on your Fortitude saving throw or are prevented from infecting anyone for 1 day, the urge passes, but the 難易度 of future saving throws to resist this temptation increases by 2. This increase is cumulative, but resets when your corruption progresses. Innocents you infect and then cure（or whose recovery you significantly assist, at the GM’s discretion） do not count toward this number, nor do those infected by others who were themselves infected before your corruption reached its current stage.
腐敗段階1：The first time your corruption progresses, any disease you suffer from becomes more tenacious. You take a –2 penalty on all saving throws to resist contracting a new disease, and your alignment shifts one step toward evil.
腐敗段階2：The second time your corruption progresses, diseases you suffer from become difficult to cure； the 難易度 of a disease you are suffering from is increased by 10 for the purposes of caster level checks for spells such as remove disease to cure you from its effects. Your alignment shifts to evil.
腐敗段階3：The third time your corruption progresses, your disease saps your free will and the GM gains control of your character.
Curing the corruption requires curing not only the underlying diseases you suffer from, but also the initial illness that triggered your corruption—this often necessitates the use of rare and elaborate treatments.
The following are manifestations of the plagued corruption.

You can quicken diseases in others.
恵み：As a swift action, once per day per 2 manifestation levels you have（minimum once per day）, you can cause one creature within 30 feet suffering from any diseases to attempt a saving throw against one randomly determined disease they are suffering. On a failed saving throw, they immediately take that disease’s damage. A successful save does not count toward the saving throws required to recover from the disease.
忌み：You take a –2 penalty to any one ability score of your choice.

忌み：The disease shortens your breath and stiffens your limbs. You take a –2 penalty on all Strength－ and Dexterity-based checks.

恵み：Victims other than you who fail their initial saving throw against any disease effect you create become sickened for 24 hours.

Your senses fail you, but the terrible disease you can inflict affords you access to the senses of those who suffer from it.
前提条件：Manifestation level 7th, infectious thoughts, miserable company.
恵み：As a move action, for as long as you concentrate, you can borrow the senses of any creature suffering from a disease effect you created, as long as the creature is within range of your infectious thoughts. Your body is effectively blind and deaf while you concentrate. The target can resist this intrusion with a successful Will saving throw. At manifestation level 9th, you can possess one such victim as per possession once per day as a standard action while you are already sharing its senses.
忌み：Your senses falter. You take a –4 penalty on Perception checks and Sense Motive checks while you are not using theft of awareness.
