Bab 79: Battle

There were five realms of spells. The weakest was the elementary realm followed by the intermediate realm and the advanced realm. These three realms are the ones considered "achievable" while the last two are called the expert realm and perfect realm which is simply a legend for almost all of the Arcane Paths. 

The expert realm had only been seen once in the past three hundred years while the perfect realm is simply something that they've seen on the records. 

Needless to say, Vale's advanced realm Ghost Hands should be something that not even the graduates of the Academy would achieve!

There may be people who were capable of doing that but they would certainly not focus their time on this support-type Dark Spell! They would rather have intermediate realm Tier 2 Dark Spell than advanced realm Tier 1 Dark Spell.
