Minor versions of Cure Disease
by LibraryOgreAnother option, instead of "Cure Minor Disease" would be to allow a second save, with a bonus.
So, the 1st tier spell might be "Panacea", and it lets the person have a 2nd save against the disease. Cast it as many times as you can, new save each time.
2nd tier is "Greater Panacea", which allows a 2nd save, with a +5 bonus.
3rd tier is Cure Disease.
For disease, especially, you might also want a 2nd or 3rd tier "Protection from Disease" spell... maybe 2nd tier will protect the caster, for 1 hour, and 3rd tier will protect several people, also for 1 hour. Immune to disease for an hour, letting you care for people (magically or medically), but without risk.
