Arcane Devotee

Every major faith numbers sorcerers and wizards among its fervent followers. While some wizards ally themselves with churches close to their own beliefs out of caution and convenience, others are devout representatives of their faith and willingly subordinate their own causes to those of their patron deity, becoming arcane devotees. Arcane devotees complement the divine magic of a church's clerical leaders and are among the most important and respected members of a deity's following. They provide much of the magical firepower of their faith and collaborate with the church's clerics in the creation of magic items requiring both arcane and divine spells. Arcane devotees provide support for the church's armies in time of war, divine the intentions of the enemies of the faith, and often take the front line to decimate enemy troops or destroy spellcasters of rival faiths.
Naturally, arcane devotees are always arcane spellcasters. Sorcerers and wizards are the most common type, but some music-oriented deities tend to have more bard devotees, and a rare few of the more evil deities have been known to have assassin devotees that focus on cruel and terrible forms of death magic.
Although clerics and druids make up the majority of spellcasters within the hierarchies of Faerûn’s churches, they by no means hold a monopoly. Many pious sorcerers and wizards, and even a few bards, choose to devote themselves to a deity as thoroughly as the most devout of clerics. These arcane spellcasters gain an insight into divine magic that often baffl es their less religious peers. Arcane devotees are most common among the worshipers of Azuth and Mystra, with the former attracting more wizards and the latter more sorcerers. Bards sometimes become arcane devotees of Lliira or other musically inclined deities, and rumors persist of assassins serving as arcane devotees of Bane.
