Torack I like your characters but you may need to change your alchemic specializations. 

Illusion is already reserved.

Also as for quantity manipulation, it may not be practical. Even alchemy has limits and while manipulating the size is possible, cloning or multiplying is a far more difficult concept. For one it will need to have limitations. While you maybe able to clone an object and increase its quantity, you will be limited to how many and the effectiveness of what you clone will be half of the original and so on. So say you have a bullet and you clone it twice, as such the second bullet will be half the effectiveness of the first and the third bullet will be half of the second.
