A magic apprentice with adept skills used the simplest and most unremarkable "Magic Manipulation" to fling a large rock through the air, successfully destroying a Walking Corpse Puppet created by Advanced Magic.
Unless the spellcaster gains a deeper understanding and utilization of this spell, enabling them to create stronger Undead Puppets.
Evidently, the reason "Walking Corpse Puppet" is classified as Advanced Magic is merely because it is more difficult and complex than most Basic Magic.
From this perspective, spellcasters studying the "Summoning School" seem to face slower progress and reduced efficacy compared to their peers specializing in the "Elemental School."
As for magic that is even harder and more complex than "Advanced Magic," such as "High Magic" and "Great Magic," it is beyond the reach of those simply researching particular academic fields.
For example, Lady Aphrodite's Netti Cards, which can indeed be considered miracles of Great Magic.
