Magic in the RWBY universe could be seen as a new form of energy. Spells like Lumos could be used to light up the dark areas filled with Grimm. Wizards might have to adapt their magic to work with Dust. For instance, a Fire - making spell could be combined with Fire Dust to create a more powerful blast.
In a crossover, the magic system could interact with the Aura in RWBY. Aura could act as a sort of shield against dark magic. Wizards might find that their magic is more potent when they have a strong Aura. However, they'd also have to be careful not to deplete their Aura while casting spells. Also, the concept of wandless magic could be explored more. Since RWBY characters don't use wands, perhaps some wizards in this crossover could learn to cast spells without wands in the RWBY world.
