Sorcerer

Sorcerers cast arcane spells through innate power rather than through careful training and study. Their magic is intuitive rather than logical. Sorcerers know fewer spells than wizards do and acquire powerful spells more slowly than wizards, but they can cast spells more often and have no need to select and prepare their spells ahead of time. Sorcerers do not specialize in certain schools of magic the way wizards sometimes do. Since sorcerers gain their powers without undergoing the years of rigorous study that wizards go through, they don't have the background of arcane knowledge than most wizards have. However, they do have more time to learn fighting skills, and they are proficient with simple weapons.
