Zelgadis nodded. "No one can master every form of magic." Well, maybe Rezo could, but he had spent the better part of a century learning. "You're one of the best white magic users I know, so you're better off trying to model your studies after someone like Amelia than someone like Lina. Maybe without Amelia's more... hand-to-hand spells, though."
Seriously, after seeing Prince Phil fight, a spell to channel magical energy into one's fists made sense for someone who had learned martial arts from Phil. But it wasn't something that Zel thought anyone without that background should copy.
