Introduction
Apeerless practitioner of lethal shadow magic, Shieda Kayn battles to achieve his true destiny—to one day lead the Order of Shadow into a new era of Ionian supremacy. He wields the sentient darkin weapon Rhaast, undeterred by its creeping corruption of his body and mind. There are only two possible outcomes: either Kayn bends the weapon to his will... or the malevolent blade consumes him completely, paving the way for the destruction of all Runeterra.
“The child is gone. The killer remains.”
Abilities
Kayn wields an ancient, sentient weapon that battles with him for control. Dealing damage against champions causes them to drops orbs that are automatically collected upon leaving combat, filling a bar above Kayn's portrait.
Once the bar is full, he can choose to either be overwhelmed by Rhaast or expel him to become the Shadow Assassin, based on whether he has damaged more melee or ranged champions, respectively. Once primed, the other option becomes available after 4 minutes. Kayn can continue collecting orbs for his other form to reduce the wait time.
The transformation can only be performed by interacting with Kayn's portrait while on the summoning platform, permanently changing his abilities.
