Okay this makes sense. 
I was thinking of adding witchcraft to the magic system. 

Witches learn power from the Ideals via a special intermediary called a Patron. A Patron is an intelligent spirit like being that represents The Ideal. While Wizards and Mages are like people who melt ice and snow to drink water directly, the Witch's Patron are like water filters. 
Boons and Hexes are spells that effect changes representing the witch's interpretation of what the Ideal is, 
but aren't always as strong as a Mage or Wizard's spells. On the other hand, the lack of potency from a Witch's spells might actually be an advantage rather than a deficit. Reality won't punish the witch as harshly as a Wizard of Mage. 

But this easier access to magic can be tempting, and is still dangerous with over use. 

 Thoughts?
