Cure Blight Disease
Removes the effects of Blight Diseases from the target. This effect is absolutely vital to have if you explore the Ashlands, Molag Amur, or Red Mountain regions, as blighted creatures are common there, and some Blight Diseases can be quite debilitating. (Black-Heart Blight in particular can stop you dead in your tracks by reducing your Strength and causing you to become over-encumbered and unable to move without abandoning gear.)
The free spell Vivec's Touch combines Cure Blight Disease and Cure Common Disease, and has a casting cost less than 1/10 what it should require, but is an on-touch not on-self spell. An on-touch or on-target Cure Blight Disease is required for curing blighted Kwama Queens is some quests, though it has no apparent effect against blighted enemy creatures or their corpses, nor against non-hostile blighted Kwama Workers. Unfortunately (and counterintuitively) it is not possible to avoid contracting Blight Diseases by curing Blighted creatures before they can attack you; the Disease infliction is a property of the attack and does not check the creature's current Disease status.
Cure Blight Disease should also be used after combat with blighted creatures for any long-term follower NPCs, like Fjorgeir or the Tribunal expansion's Calvus Horatius. NPCs can catch diseases and have their stats silently but negatively affected. This must be done by spell or item, as such NPCs will not take curative potions (even Calvus, with whom you can do inventory sharing). Short-term followers need not be cured (it won't affect their quests or dispositions), but you may wish to do so for roleplay reasons.
