Playing as Jarvan IV
Tips to maximize your impact
- Flag first, then lance
Plant Demacian Standard (E), then cast Dragon Strike (Q) toward it: you fly to the flag and knock enemies in your path into the air.
- Start with an auto
Land an auto as soon as you reach your target: Martial Cadence (passive) adds damage based on their current health, then only triggers on them again after a few seconds.
- Trap a carry in your arena
Cast Cataclysm (R) on a carry who is away from their team: the arena is impassable, and you can recast to collapse it if it gets in your allies' way.
- Plant your flag near your allies
In teamfights, plant Demacian Standard (E) near the allies who are attacking: it gives them attack speed while they stay close to it.
Playing against Rengar
How to counter and exploit weaknesses
- Stay away from brush
Stay away from brush in lane: from a brush, Unseen Predator (passive) lets him leap onto you with a single auto.
- Trade when his Ferocity is low
Take a trade when his Ferocity is low: at max, his next spell is empowered, and Bola Strike (E) roots you instead of slowing you.
- Group up when he's hunting you
Move closer to your allies as soon as an indicator appears over your head: Rengar is hunting you, camouflaged, with Thrill of the Hunt (R).
