Tips

  • One Red Kayn build uses lethality, with omnivamp or other sustain from augments or prismatic items when needed for extended fights against tank or healing-heavy lobbies.3
  • Mystic Punch, Reverberation and Firebrand together on Red Kayn can keep opponents airborne while burn stacks.4
  • Energized builds are a favorite for mobile poke champions such as Blue Kayn.5

Interactions

  • Blue Kayn's W with Red Kayn's knock-up sounds like a nasty combination.6
