There are five basic functions of Animas: Start, Seperate, Spread, Amplify, and Transform.
Start allows someone to create an image of theirAnima to fight. These images are made of pure energy, and have different effects depending on the user.
Seperate allow the user to create mutiple images of their Anima. Each of these images has the same amount of energy in them as the original, so it makes for a much stronger attack.
Spread allows the user to put their Anima into an object, which is usually thrown to increase the range of their attacks.
Amplify is where the user increase their bodies efficency with Anima, partially transforming into it. This gives them certain useful body parts, such as gills if you're a fish, or wings if you're a bird.
The Transform skill allows the user to change certain aspects of their anima, and focus on them, such as the speed or speed.
There are also other skills, which not everyone can use, and some can only be used by a certain anima.
