Astral divination

Astral divination was a kind of magic practiced by Noble Centaurs, and could reproduce the effects of both divine and arcane magics.

Most spells cast by centaurs using astral divination required an invocation of a particular heavenly body or constellation, which they named and/or traced with one hand if it was not visible. Certain crystals seemed to focus this power, perhaps by capturing starlight. It was unknown to outsiders how centaurs bonded with the celestial power of stars and other objects.
