Based on this post here. Basically, Zexion and Donald have similar stats in 358 Days. HOWEVER, Donald’s magic stat is ONE point stronger than Zexion’s.
“Just admit it! I’m the better wizard,” his insufferable rival
squawked, proudly puffing up his feathers and patting the head of his mage’s
staff. Littering the ground around them were the charred and battered remains
of eleven training dummies. The duck had managed to score the last hit and thus
had beaten him by one point. Again.“For the moment,” Ienzo replied, a frustrated scowl marring his
usual mask of indifference as he snapped the lexicon shut with more force than
was necessary. He let the weapon vanish before crossing his arms over his chest
and narrowing his eyes. “But I will surpass you, even if I have to spend
the next three weeks studying every magic-related text in the library and
practicing every known casting technique. So go ahead and gloat while you can.”Three weeks later, Ienzo fought the overwhelming urge to bash
his head against his desk. Repeatedly.“So I heard the duck showed you up again,” Lea casually remarked,
leaning on the bookshelf in the corner of the study. “That’s too bad. And you didn’t even get a
consolation prize? You deserve a gold star for effort, in my opinion.”Ienzo shot Lea a dour look before addressing the third occupant
in the room. “Aeleus, would you kindly escort Lea out the door?”Said redhead gestured innocently. “Hey, I’m just trying to
lighten the mood a little. So what if a talking duck is more
skilled at magic than you? At least you’ve got him beat in the height
department, right? Congratulations, you’re no longer the
shortest one in the castle!”“…On second thought,
Aeleus, the third story window to your left should be just as effective.”
