Playing as Kayn
Tips to maximize your impact
- Pick your form based on their team
Take Rhaast against a tanky team, Shadow Assassin against squishy targets: The Darkin Scythe (passive) gives one healing, the other bonus damage at the start of fights.
- Gank through walls
Gank through walls with Shadow Step (E): you move through terrain faster, and you heal when you first enter it.
- Hide inside an enemy
To dodge a burst, cast Umbral Trespass (R) on a champion you just hit: inside, you're untargetable while your spells come back up.
- As Rhaast, hit everyone
As Rhaast, hit as many champions as you can with your spells: The Darkin Scythe (passive) heals you for part of the ability damage they take.
Playing against Sejuani
How to counter and exploit weaknesses
- Dodge her charge
Dodge Arctic Assault (Q) to the side: enemies it passes through take a knock-up, and the charge stops on the first champion hit.
- Leave before her second swing
Get out of range before the second swing of Winter's Wrath (W): it deals most of the damage and slows.
- Watch her melee allies too
With Frost stacks on you, watch out for her melee allies too: their autos apply them, and at 4, Permafrost (E) stuns you.
- Don't be first in her bola's path
Don't be the first champion in the path of Glacial Prison (R): that champion is stunned, longer if the bola comes from far away.
