Cause disease once/2 levels per week. The disease may be one method/four levels. The methods are:

Ingestion
Inhaulation
Skin-to-skin contact
Blood infliction
Method X (20th level only; a disease so horrid it is beyond class 4 (Can get through Haz-Mat suits, survive the vacuum of space without dormancy, is not harmed by fire and has an instant incubation period.) The DC to overcome a disease is 10 + 1 / 2 levels.

The damage per day is 1d4-1 (lvls 1-4); 1d4 (lvls 5-8); 1d6-1(lvls 9-12); 1d8 (lvls 17-20) or the disease may cause 1d4 (1-5); 1d6 (6-10); 1d8 (11-15); or 1d10 (16-20) points of depleation in attribute scores (i.e. at if you get a 4, you chose 4 points to subtract.) This ability drain is one time only and not per day.

If the depleation causes a score to reach 0 the following happens:

Str - Complete nervous shut down. Dex - living Rigor Mortis. Con - Death. Int - Vegetable-like state. Wis - Trapped in an endless Hellish nightmare. Cha - Coma. CoP - Your powers flair up to maximum potency for 1d4 rounds before this power is negated forever. This could for instance depending on the Narrator mean simply a real big fireball or that you have a premature cremation.

Incubation Period -
30 days (lvls 01-05)
15 days (lvls 06-10)
10 days (lvls 11-15)
05 days (lvls 16-20)
