Diseases

Spoiler Warning: This page contains spoilers which may affect your IVAN experience negatively

Diseases are technically states like ESP and Infravision are, but they are never shown to the player on the HUD. A player must notice the cues by paying attention to the message box in order to tell whether they have been infected.

Leprosy

You feel you're falling apart.

This disease will abuse player's attributes over time, and most importantly, will cause limbs to drop off one by one in random intervals. Leprosy is mostly associated with Zombies.

You can contract leprosy from the following sources:

• Eating meat infected with leprosy.
• Being near or attacked by a leprotic monster.
• Putting back an infected body part.
• Angering Scabies with your prayers.

Leprosy can be cured by drinking antidote liquid, by any Priest or through prayer to Seges. Also, leprosy is tracked for each limb individually, so reattaching an infected limb (for example if you lose an arm due to leprosy, cure the leprosy by paying a priest and then let the priest reattach the infected arm) will infect you again.

You are not falling to pieces anymore.

Lycanthropy

You notice you've always liked full moons.

This disease will polymorph you into a Werewolf occasionally. Obviously being bitten by a werewolf can cause this, but it can also be contracted by eating werewolf flesh or as a magic effect from drinking fountain water.
It can only be removed by priest or priestess - it will not be removed by antidote liquid.

See Werewolf Fur Cloak for a CLIVAN artifact that grants this disease.

You feel the wolf inside you has had enough of your bad habits.

Parasite

You feel you are no longer alone.
Ugh. You feel something violently carving its way through your intestines.

You have been infiltrated by a parasite. Every time the message above appears, you lose some HP.

Right now (as of IVAN 0.50) there are two types of parasites, the latter being more difficult to get rid of by means of vomiting:

• Tapeworms
• Broad tapeworms

You can get contaminated by multiple reasons:

• Eating spoiled food.
• Kobolds and Goblins might have them, so don't eat them if they're rotten.
• Drinking from a fountain may cause this.
• Eating a Black Unicorn corpse.

You can get rid of parasites by:

• Vomiting until the game says that you notice the dead parasite in the vomit. ("You notice a dead broad tapeworm among your former stomach contents.")
• Drinking antidote liquid.
• Ultimately, if the previous won't help, by drinking Sulphuric acid. That will kill you though, if you don't have extremenly strong acid resistance.

A feeling of long welcome emptiness overwhelms you.

Teleportitis

See Teleport.

Polymorphitis

See Polymorph.
