Ether Disease is a series of random corruptions that you receive over time, similar to mutations. Unlike mutations, each disease symptom either has an entirely negative effect, or both positive and negative effects at the same time. It is possible to get the same symptom twice; however, depending on the corruption, this may or may not have any effect.
You can slow down the rate of the ether disease advances. This is done by:
- Wearing equipment that protects from the Etherwind such as the Vindale cloak, Shena's Panty, or Hero's Cloak.^
- Being an Elea.^
The rate of the disease also speeds up by:
Something of note is that the ether disease, at least, outside of the Etherwind, a certain amount of time has to have passed since you last saved/loaded your game before a corruption can occur. This presumably happens to stop someone who saves (either intentionally or by accident) right before an ether disease corruption was about to take place from savescumming to try to get only the ether diseases they want to get. Hypothetically, you can delay ether disease quite a while by simply saving and exiting and then reloading to prevent the game from determining you have played long enough without saving to spring the next corruption on you.
The only way to cure ether disease is by using a potion of cure corruption, which will remove no more than the last three symptoms, unless when it is cursed. (In Elona+ 1.88R, it can also be fused into the food item "cure crystal" which removes the most recent symptom.)
If left untreated with many (20+) symptoms, you will eventually die from the disease. If you die in this way and choose to continue, the last disease effect will be undone, but you'll likely die again in the next Etherwind or simply after enough months go by if you don't drink a potion of cure corruption.
Although the disease is "very common in Irva" (according to Norne the guide), allies, and other NPCs, do not get the disease (with rare storyline exceptions), and can safely wear ether equipment. Because such equipment is always fireproof and acidproof, and each item raises Speed by 5, they might even be ideal for pets until better artifacts turn up.
The specific values of ether disease effects scale with your stats; for example, getting a huge head for a wizard will add much more learning than for a golem warrior.
