Swirling Fire

A circle of illusory fire forms around your hand as you point. The caster can use one hand to sustain the spell, and their off hand has the power to resize the circle. The circle can be as  small as a bracelet or as large as a round shield. Regardless of size, the fire emits no heat but sheds bright light in a 20-foot radius and dim light for an additional 20 feet. The fire can be colored as you like.
