The moment the berserker potion mixed with his blood, Michael's eyes took on a slight crimson glow as his muscles bulged under his armor. His pupils contracted, and he grew a few inches taller and more robust. Michael had never needed the potion while he had access to celestial energy, but with Mugashuku's void effect nullifying celestial energy, he resorted to the berserker potion.
Michael typically avoided using the berserker potion because, after its effects wore off, his body would be weakened for a period. However, in this dire situation, he needed the potion's boost to contend with the mysterious energy powering Harriet.
Noah, an alchemist himself, immediately recognized the potion. Deep down, he was shocked that Michael had managed to brew this notoriously difficult concoction.
"I didn't want to do this in front of his mother, but if you insist, then so be it," Michael growled, slowly advancing toward Noah and Harriet.
