Dispel Magic

This spell is very similar to the "Cure" spell, but more versatile. Unlike Cure, the spell not only heals poison or bodily malfunctions like Paralysis, but also can awaken people and, most importantly, can also dispel evil magics, such as Charm, that were placed on that person.

Of course the spell only works on a single person. For the whole party, Mass Dispel is needed.
