In some works of fiction, there are two kinds of Magic. Arcane Mage, and Divine Magic. Arcane Magic is gathered from the Universe and it's Ley lines and such.

Divine Magic is drawn from worship to a deity, or a concept. For example, Clerics of a god who use Magic are using Divine Magic.

These two types of magic have differences in what spells they produce, and in a few cases, Arcane Spells will fail if the caster is wearing armor, but not divine magic.

In short, your Character must be better at Arcane Magic than anything else.
