Currently the spell Dr. Von's Monster leaves an infection that reduces heals by -25%. This is not nearly enough. -25% to a heal is negligable, and counts very little as a secondary effect. The spell should be made so that it leaves a -90% infection, sort of like Efreet, only with heals. Given the limited use of infections, it only makes sense to make the Dr. Von's spell give an infection that actually has some effect on gameplay, and reflects the power that a Death wizard commands at that level.
