	Pretty decent work, I will give an example when it comes to the Slave Magic. For example, creatures like Slimes can be contracted fairly easy thanks to the fact their pretty much mindless creatures on their own. But an intelligent creature like a special bird that might show up, requires one to impress it with music before one can contract it. (Note: if you ever read 'Man picked up by many gods' then you might understand what I have in mind for slave magic)

	Upside to Slave magic Vs Summoning Magic, Slave magic creatures can be trained to become stronger, and certain creatures can even evolve into new forms, and are 'normally' entirely loyal to their master, and have spells that can expand on this bond. Summoning Magic creatures can't grow stronger than when they are summoned, and sometimes might disobey their master since the contract to fight is a forced one-sided way, but the Variety of creatures aren't limited to a person's specific aptitude and don't have to worry about caring for the creature in question. 

	So think of a type or two of creatures for her aptitude for slave magic. Meaning she can contract this type of creature a lot easier than others. -Note: the applications of this is very spread apart and have various meanings, can be a specific creature type, to creatures with this certain feature. Example for slimes: aptitude for creatures that are weak on their own, but are strong with grouped up. of course this also refers to other creatures with similar circumstances.
