Eternal Diarrhea

Your touch inflicts disease.Make a melee spell attack against a creature within your reach.On a hit the target is infected with explosive diarrhea and projectile vomiting.The diarrhea actually explodes and the vomit can hit things in other buildings.You have disadvantage on all checks and saving throws except performance and persuasion checks that relate to this disease,deception checks about convincing people that this disease is more serious than it really is,intimidation checks and constitutional checks(NOT CONSTITUTION CHECKS BUT INSTEAD CHECKS ABOUT POOP).If anyone except you and the source of the diarrhea gets hit with the projectile vomit or goes within5feet of someone infected they are infected with it to(the reason going within5feet causes you to be infected is because of diarrhea).After this sentence"you"refers to an infected person and NOT TO THE SPELL'S CASTER!If someone who is already infected gets hit with the projectile vomit or goes within5feet of someone else infected the duration of the disease increases by2days you are only infected by getting to close to someone that is infected when you either stop being within5feet of someone infected or the duration expires and the infected person within5feett of you either stops being infected at the same time as you or after you do.All infected creatures can't eat or drink anything and gain no benefits from any rest.If anything would become infected if it was a creature then it becomes contaminated if a creature touches and/or eats and/or drinks something contaminated the disease incubates for2weeks.Contaminated objects remain contaminated for2weeks.Air can't be contaminated.There is no protective gear that will do anything to protect against this disease and protective gear including shields and armor don't even cause there to be an incubation period.There is nothing you can do to stop the disease but wait.During the incubation period there are no symptoms and it spreads during the incubation period exactly like after it's over except anyone infected by someone during the incubation period's incubation period will be the same as the amount of time left on the infector's incubation period the same thing applies to those infected by objects contaminated during the incubation period.Objects contaminated by those not in the incubation period will be clearly contaminated either brown from diarrhea or green from vomit.Objects contaminated by those in the incubation period will be indistinguishable from non contaminated objects unless they are contaminated with poop then you must succeed on a DC17 wisdom perception,wisdom medicine,wisdom survival or intelligence investigation check to discover the contamination.If a contaminated object touches a liquid then the liquid becomes contaminated and indistinguishable from the non contaminated version of it and the incubation period becomes1hour.For every20creatures infected1of them after the symptoms go away will infect and contaminate for3weeks afterwards exactly the same as during the incubation period except with a50 foot radius and a2hour incubation period.If a year has passed since this spell was cast and the disease from this casting of the spell still exists in any form the caster can now be infected with it.The infected can't do anything for an action or bounus action except dash to the nearest toilet.Every day the infected take3damage.after2weeks of symptoms infected creatures can make a DC17Constitution save every day until a successful save is made on a success the symptoms end.On a fail nothing happens.This disease CAN'T be cured or prevented even by magic!
