Disease is an affliction commonly borne by cockroaches and rats. It can be also contracted by traversing on swamps, in poisonous atmosphere (such as Skylark Vale's caverns) or by being close to corpses in advanced state of decomposition. A disease wastes away the victim, eating their health until they are withered husks. However, unlike poison, acid or other comparable magical afflictions, common disease is never deadly on its' own.
The affliction can be cured by application of magic, curing potions or other curative items such as magical scrolls. However, recent studies have shown that the amount of outbreaks within the world of Ermarian in general has drastically reduced. Scholars have surmised that this can be attributed to advances within the fields of hygiene, first aid and increased education.
