In Channeling Companion one may read the following about ghouls and ghoul rot.
"Those infected with Ghoul Rot do not heal naturally (magical healing spells are equally ineffective), in fact they will lose 1-5 hits a day until death
claims them. Only a Cure Disease or a Remove Curse spell will remove the affects of this infection."
IYO, would the 13. lvl spell on arcane healing, Undisease, suffice to cure the ghoul rot? Or is it only the two spells mentioned in the text that will do. Do you need some sort of cure disease spell, or the Cure disease spell?
Our group just ran into a group of ghouls in a part of the world where there are no channeling users.. sigh..
