Like clerics, favored souls have access to powerful healing spells. Favored souls and sorcerers get more spell points than any of the other classes. They also gain more bonus spell points from special magic items. As a result, they can cast more often.
Favored souls cannot switch spells at taverns or rest shrines. They are able to switch spells but to do so they must undergo a special ritual that can only be done once every few days.
Wielding divine magic to both heal and destroy, favored souls have fewer spells than clerics but can cast more often.
All simple weapons (plus longsword, rapier, short sword and shortbow), light armor, and all shields except tower shields.
