the white mage heal isnt aspected its just drawn from the elementals or however they were called, The astro is from the stars which again its not really aspected its just drawn from the constelations corresponding to the twelve, the sch one though is completely unaspected its just arcanima and its completely different cause it doesnt draw from anything, something that if i remember whms thought impossible , or more likely a death sentence judging by the conjurer quests i dont remember well.

arcanima is basicly expressing or replicating everything through maths and geometrical symbols, so basicly a circuit and aether is the electricity , which is why by simply having a piece of aether you can learn how the target is and fix them. in the same principle an arcanist can summon only this time instead of replicating the piece missing to mend them you replicate the whole target thus summoning them , the arcanist uses info from gems to summon the carbuncles , while the summoner takes the true essense of primals to summon the egis the same way he would a carbuncle.
