The weakest healing spell, and also the only healing spell for knights for many years until Wound Cleansing was introduced in late 2007. The number of hp it can heal depends upon your level and magic level (and is around 1/10th of your UH power). It is useful if you are trying to raise your Magic level or to get rid of Paralysis. Knights can't use it since Winter Update 2010. Since Winter Update 2012 this spell is free. It used to cost 170 gp.
