Some people may not know this, but instead of using cure disease potions or going to a chapel and using any of the 10 alters, you can alternatively use garlic. It can be harvested with relative ease from a hanging cluster found in several areas, including the basement of Rosethorn Hall. Its default 1st effect is Cure Disease, and even better, it is weightless, and therefore can be held in vast amounts.
No it's first effect is ressist desiase.
