Following up on my Comprehensive List of Diseases in 4th Edition, the following is a compilation of many diseases appearing in 3rd party sources. They are listed here broken down first by level for easy reference and then, in a separate set of tables, by publisher, so you can quickly see what diseases are available in the books you have.
THIRD PARTY PUBLISHERS – DISEASES BY LEVEL
| LEVEL | DISEASE | DESCRIPTION | SOURCE |
| Lvl 01 | Chimney | A nuisance at most, sufferers exhibit a loud, dry cough, and breath that smells like soot. | |
| Lvl 02 | Couplet (Curse) | Your curse compels the target to speak in rhyme, to your great amusement and their tongue-twisted dismay. | Hero’s Handbook: Eladrin (p.36) |
| Lvl 02 | Hobbles | Victims of hobbles suffer from swelling of the extremities, tenderness of the feet, and joint pain. Walking becomes uncomfortable and running painful (if not impossible) as the disease progresses. | Monsterecology: Orcs (p.29) |
| Lvl 02 | Tumbledown | Often spread when the target swims in or drinks tainted water, the disease causes severe vertigo and makes it impossible for the sufferer to stand. | |
| Lvl 03 | Dark Rot | Some say this disease was created in Morgau as a means to speed the living onto the land of dead. Dark Rot appears at random, so its contagion is still not fully understood. | |
| Lvl 03 | Iron Rot | Rusted metal of all sorts, from old sword blades to discarded nails, carries iron rot. The victim’s joints slowly stiffen until movement of any kind, even speech, is impossible… | |
| Lvl 04 | Night’s Delusions | This disease travels on the blades of weapons. At first, sufferers feel a sense of elation, but this gradually leads to dreamlike illusions. | |
| Lvl 04 | Skinpaper | The sufferer’s skin becomes dry and rigid, tearing open at the least scratch. The final stage causes the infected person to suffer horrible wounds when injured. | |
| Lvl 05 | Bloat Gloom | So named because the target’s face and limbs swell noticeably, the disease deadens pain from physical injuries and makes the sufferer oblivious to the severity of his wounds. | |
| Lvl 05 | Trasmute Emotions (Curse) | Your curse robs the target of all normal feelings. You choose to replace all of the target’s emotions with giddy joy and laughter, or deepest misery. | Hero’s Handbook: Eladrin (p.36) |
| Lvl 06 | Blood Rotting Sickness | Any cut from centaur arrows taints the blood and leaves victims feverish and weak. | |
| Lvl 06 | Bonewrack | Spread through insect bites, this disease causes horrible joint pain. A confounding illness, bonewrack seems to get worse just before the target recovers. | |
| Lvl 06 | The Fugue | Stale tomb air and fouled water transmit the fugue. Those afflicted report waking up in places or circumstances in which they have no memory of entering. | |
| Lvl 07 | Blue Ague | Carried on the foul vapors from sewers or through food, this disease befuddles the mind, causing the sufferer to act as if in a torpor. | |
| Lvl 08 | Angel Fire | This disease is so named because the sufferer’s flesh burns with radiant energy that only worsens in the presence of healing magic. | |
| Lvl 08 | Larval Infestation | | |
| Lvl 08 | Sailor Fever | Often thought to be the reaction of a sailor who has lost his mind after too many days at sea, this disease spreads through flea and tick bites and manifests anywhere those vermin are plentiful. | |
| Lvl 08 | Searing Fever | The symptoms of searing sickness include fever, extreme headache, joint pain, and blindness. | Monsterecology: Orcs (p.34) |
| Lvl 09 | Bleeding Blights | Thinned blood causes the victim to bleed profusely from even the slightest wound. | Critter Cache 4: Fey Folk (p.14) |
| Lvl 09 | Necrophage | | |
| Lvl 10 | Fool’s Cap (Curse) | Your curse gives the target an ass’s head, matching external reality to essential truth. | Hero’s Handbook: Eladrin (p.36) |
| Lvl 11 | Tremors | Contracted through addiction to Requiem, this disease is marked by sweating, vomiting, and un- controllable muscle spasms. | |
| Lvl 12 | Bauble (Curse) | Your curse causes the target to prize the possession you des- ignate over all other things, an obsession that quickly grows into madness. | Hero’s Handbook: Eladrin (p.35) |
| Lvl 14 | Feral Hunger (Curse) | Your curse causes the target to become revolted at the sight of ordinary food and crave grass, hay, or blood instead. | Hero’s Handbook: Eladrin (p.36) |
| Lvl 14 | Fungal Infestation | This disease infects the target with a virulent strain of fungal growth. The fungus slowly poisons the target, and creates a severe, and potentially deadly allergy to sunlight within its host. | |
| Lvl 15 | Thew Blight | A particularly horrid disease, thew blight slowly liquefies muscle tissue until the victim is little more than immobile lump of wither flesh. | |
| Lvl 16 | Madness of the Wailing Wind | The insidious wind whistles in your ears, whispering blasphemous secrets impossible to ignore. | Kobold Quarterly 11 (p70) |
| Lvl 16 | Spetic Death | Rampant, flesh-eating bacteria devour the victim from the inside out. | |
| Lvl 22 | Gaes Curse | | |
| Lvl 22 | Skinchanger (Curse) | Your curse causes the target to spend half of each day as an ordinary animal with animal intelligence and instincts. | Hero’s Handbook: Eladrin (p.36) |
| Lvl 25 | Cannibal Curse | You are overcome with a terrible desire to eat the flesh of your own kind... even if you have |
