link toting the master sword and his wedding ring,
He has the ability to charge the master sword with his ki which is infused with the holy light, from his heritage being the offspring of one of the hylian princesses who hold the power of goddess hylia herself,
Injecting excessive amounts of energy into the blade changes the color of the master sword's blade from a bluish white to a glowing gold, doing this makes the blade temporarily much stronger making the strikes even more effective, the origin of this transformation comes from the master sword's innate property allowing it to grow in strength or repair itself when bathed in holy light, the blade would originally glow a bright blue when powered up but over time due to being bathed in link's energy over time it evolved reaching transcendent levels of power allowing him to cut things lacking a physical form like concepts or the very Laws that hold the very world together, this makes him and the master sword a deadly team to handle.
