The source of divine magic is still yet to be explained. Most gain their divine powers by nothing but sheer devotion to their deities. Stories tell of a crazed cult that began worshiping nothing but a old boot. The boot began to glow with a divine energy and those who worshiped it gained divine powers.
Divine spellcasters tap into the power of patron deities or other powerful divine forces to achieve similar effects as those who unlock arcane spells. Though often the divine spellcaster needs a focus of his faith such as a holy symbol, there are often gestures, words, and material components that accompany the casting of a divine spell as well.
