in wheel of time i have disease sites all over the goddamn place. big deal. I even have one of my major centres plop on top of one. Disease can be a pain early on, but if you have half an eye it will be obvious that there is one there, as mages don't get diseased for no reason.
Micah: i can assure you that there are a number of non lvl 0 disease sites - plaguewater stream, leper fens, pool of unearthly rites, chillsick... most of which I have
leper fens is the one you want to avoid - 10%
