D&D 4E 4E Disease and Sickness Collection

[SuperGnome]

Hey all,

I thought I'd start a collection of diseases and sicknesses people created so we all have one resource to pull from. The DMG has just a few examples, and those start at 9th level! Please post your complete diseases (last until cured) or sicknesses (possibly duration based) with Name, Level, Type, a short description of where it's commonly found and the affects of it.

Abyssal Utterance
Level 3 Disease
Fortitude Attack: +6
Endurance Improve DC: 16
Maintain DC: 11
Worsen: 10 or lower

Stages of the Virus
0: Target is cured.
1: Initial Effect Target may only speak Abyssal.
2: Abyssal Tumor grows on the host's body. This growth has sentience, and begins to effect the host's mind. -2 to Will Defense, lose 1 healing surge.
3: More, powerful tumors spread. The host takes -2 to Fort. The Tumors begin influencing the host more, subconsciously encouraging the host to spread the virus to as many uninfected individuals as possible. Host will also refuse to succumb to a Cure Disease or Remove Affliction ritual.
4: Final Stage The Tumors' control of the Host's will has become complete; an entity that can possess targets does not need to succeed in an attack to possess the Host. Furthermore, the Tumors have gained enough power to connect to the Abyss; the Host has a 15% chance per day of being possessed by a demon from the Abyss.

Contraction

Abyssal Utterance is an utterly wicked plague, not only due to what it does to a victim, but how it is spread. The first symptom of the virus is that the host speaks Abyssal (but does not understand it, unless the host knows the language all ready). Anyone who hears the infected host speak is exposed to the virus.

Ulterior Motive

The actual infection is not the final threat of the virus. Certainly an outbreak ending in an infected population who are possessed is bad enough. But the actual words in Abyssal are a threat. If enough entities are speaking at once, there is a significant chance that demons can be summoned from the Abyss. The Tumors are aware of this, intentionally infecting hosts and coordinating until they have enough to carry through a summons.

Crotch Rot Disease

Haven't used it yet, but this is something I put together to use after the party deals with an elite custom monster - a large Black Widow spider.

During the encounter, track who is hit by the Black Widow’s bite attack. Let each one of them know that they are starting to feel weak and they are affected by the disease Black Widow’s Poison.
Black Widow Poison
Level 10 Disease
The bite of the Black Widow is known to incapacitate a man in a number of days.
Attack: +13 vs. Fortitude
Endurance: improve DC 27, maintain DC 23, worsen DC 22 or lower
The target is cured
Initial Effect: The target loses one healing surge that it cannot regain until cured.
The target’s speed is reduced in half and takes 10 poison damage after any rest.
The target is paralyzed.

This thread is awesome, I couldn't let it die

Death
Level 1-30 disease
Attack: None
Endurance: None

The target is alive (Can only be acheived with a raise death dead ritual or similar effect)
Initial effect: The target is dead
The target is more dead (Occurs after 100 years)
The target ceases to exist (Occurs when all of existence ends)

Death is spread by being reduced to negative half of your full hit points, or failing 3 death saves.

Kudos

Nice stuff there but the DC's are high compared to the official diseases. From a quick glance through the DMG and MM it looks like Improve DC's are 10+level, Maintain is 10+level/2 and Worsen of course is Maintain-1 as a rough rule of thumb.

"Filth Fever
Level 3 Disease
Endurance stable DC 16, improve DC 21"

Taken from MM1, PG 180

Unless I missed some errata, I think you may need to look more closely. I'm not sure if there's a set way of making dieases, but that's not it.

I needed two for an upcoming encounter in a mushroom forest. One is what happens when you inhale spores from a puffball.


Puffball Spore Infection, Level 7 Disease
+10 vs Fortitude
0. Cured
1. Initial State: Target takes a -2 penalty to attacks
2. Target loses one healing surge that cannot be regained until cured
3. Final State: Target is slowed.

Improve DC 20, Maintain DC 18, Worsen 17 or less

The other is the addiction brought on by eating Feywild bluecap mushrooms which give you an extra action and do not count toward your daily magic item use limit.

Bluecap addiction, Level 8 Disease
Upon eating more than one bluecap between extended rests:
0. Cured
1. Initial State: The target begins each day with no action points.
2. The target may not gain action points.
3. Final State: The target is dazed.

Improve DC 24, Maintain DC 20, Worsen 19 or less

Check Endurance every short rest and every extended rest. Every extended rest that the target is addicted beyond the first, Endurance checks gain a cumulative +1 bonus.

At any time upon ingesting a bluecap, the target may decline the extra action and instead move one step closer to cured (though it may not be cured). But if the target accepts the extra action point, the target moves closer to the Final State.

Exactly - a rule of thumb. Given that the Dcs of the diseases I was comparing too varied quite a bit I decided to make my conversions on the high side to give them that added 'punch'. I adjust DCs all the time for may of the things I find in official products (like the skill challenge chart 5 minutes after I looked at it).
