Domination improves burst damage and assassination tools on Pyke. Most of high elo players – and our LoL pros in the the major regions – have agreed that
Hail of Blades is the best keystone rune to run on
Pyke. This keystone rune helps you to win short damage trades in your lane by increasing your attackspeed at the beginning of a fight. This is usually followed up by taking
Cheap Shot,
Zombie Ward and
Ultimate Hunter.
Cheap Shot makes you deal more damage to enemies with impaired movement, which has great synergy with the setup of Pyke.
