That's more difficult to summarize than you might expect. Magic is capable of all sorts of things, depending on the wielder. Conjuration, enchantment, divination, healing— there's no shortage of possibilities, though I confess that healing and the like is better left to clerics or druids. That sort of magic tends to be divine-inspired, but the rest? A wizard draws on the power of the Weave as a musician relies on their instrument: it is the combination of the two that makes music or magic.
