circle magic

"Circle magic is a type of cooperative spellcasting that allows the spellcaster leading the circle to increase her caster level significantly and achieve results otherwise unavailable to the spellcasters composing the circle. The Red Wizards of Thay en de Witches of Rashemen make frequent use of circle magic. Stories of other forms of circle magic abound in Faerun."
