Playing as Rek'Sai
Tips to maximize your impact
- Bite at full Fury
Save Furious Bite (E) for when your Fury bar is full: the bite then deals true damage.
- Un-burrow under your target
Come out of the ground with Un-burrow (W) under your target: they and nearby enemies take a knock-up, so you can engage or interrupt a channel.
- Void Rush a wounded target
Cast Void Rush (R) on an enemy you damaged in the last few seconds: untargetable, then unstoppable, you lunge at them, and your Un-burrow (W) comes back.
- Burrow to cross the map
Cast Burrow (W) before crossing the map: your Tremor Sense reveals to your team nearby enemies who move unseen.
- Dig your tunnels in advance
Dig with Tunnel (E) near lanes to gank and on your escape routes: each tunnel lasts and can be reused, but an enemy standing on an entrance destroys it.
Playing against Kayn
How to counter and exploit weaknesses
- Dodge his Blade's Reach
Dodge Blade's Reach (W): Umbral Trespass (R) can only target a champion he just damaged, and this ranged hit is how he marks you from range.
- Save your CC for his E
If you have CC, land it during Shadow Step (E): once immobilized, he loses the spell and can't move through walls anymore.
- Save your spells for his exit
Don't cast your spells during Umbral Trespass (R): hidden inside your ally, he's untargetable. Save them for when he bursts out.
- Ward your jungle too
Ward your jungle too, not just the river: Shadow Step (E) lets him go through walls and show up from unexpected paths.
- Pressure him before he transforms
Pressure him before his transformation: until he picks Rhaast or Shadow Assassin, The Darkin Scythe (passive) gives him no healing or bonus damage.
