You are a host to an infectious disease.
Prerequisite: Disease Immunity
You may choose one disease you have gained immunity to through the prerequisite feat. If you are exposed to this disease you become a carrier of it within 2d6 days.
Depending on the type of infection, you may infect others with it in a number of ways.
To spread an ingested disease you must sustain damage from a bite attack.
To spread an inhaled infection you must use a full round action to breathe out a lungful of infected air. This cloud remains in place for a number of rounds equal to the carrier's Constitution modifier, though a moderate wind (11+ mph) or higher disperses it immediately.
To spread an infection through injury you must make a bite attack against your opponent. If you do not have a natural bite attack you can still attempt to infect. You may attempt a bite attack with a -5 penalty, granting an attack of opportunity, that deals 1 point of damage plus the disease.
To spread a contact disease you must make a touch attack against your opponent.
The DC of this disease is equal to 10 + half your HD + your constitution modifier.
If you are the target of a spell or power that heals diseases you lose the ability to infect until you are exposed to the disease once more.
You can bend in ways you were not meant to.
