Legacy

Rowan blasting away the Eye of Time using Sundown also shattered the Cherubim, grievously injuring the Angel, but not killing him, as higher dimensional angels were almost impossible to kill, he had channeled enough energy to kill a thousand Staffs and a thousand Andar, yet this Cherubim was only broken when he struck the Eye of Time with it, however, all was not lost, he would heal and Rowan smoothly swapped Sundown with Legacy, and except for an imperticible blur there was almost no way to know he had just swapped weapons.

Sundown's unique trait was his ridiculous speed, and as for Legacy, he could hold all the powers of the other Cherubim, he was the pivot around which the rest revolved. Using this trait, Rowan had perfectly transferred all the energy from Sundown to Legacy without wasting a single iota of energy, and not delaying his assault by any metric.
