While Billy didn't want to throw away the armor, Edward gave him since its effects were that amazing. Still, he needed some upgrade… One crazy upgrade that would put Billy way ahead of his enemies. His idea was to make a magic armor that would have a core that would have the same power as the core of the Golems he created, and it would use that mana to power up his physical abilities. The more mana, the more power he would get, and thus, he would use his own mana to focus on magic… Billy was envisioning something quite insane, but it couldn't be helped. He reached a point where he had too much to lose. So, he had to go all out in order not to lose anything…
