Reconstruction & Deconstruction Alchemy (Amos Only)

Deconstruction:
Amos' method follows the cyclical flow of transmutation, but only takes into account the first two steps - comprehension and deconstruction. By "stopping at the second step", the physical structure of whatever he targets is broken down and not reshaped, essentially reducing it to formless debris. By applying this method to his victims, he destroys their internal systems instantly while circumventing both Human Transmutation and the Ishvalan stigma associated with giving new form to one of God's creations.

Reconstruction:
Through his father Amos was gifted with Reconstruction Alchemy, fulfilling the circle with his deconstruction arm. While he's fairly new to both uses this is by far the hardest one he has to master.
