When Is Jarvan IV Strongest?
The mid-game item window is the high point of the curve, and games at this rank average around 28 minutes. Jarvan IV wins by making picks and starting fights on his terms, so use the strong window to gank lanes, flag onto isolated targets, and trap the enemy carry where his team can delete it.
Jarvan IV Item Build
Jarvan IV is an engage bruiser who leaps in, locks a target down, and lets his team clean up the arena he builds. The build mixes health, armor, and enough damage that his flag-and-drag combo threatens squishies while he stays sticky through the fight.
Best Jarvan IV Runes
Conqueror is the standard setup, and it matches how committed Jarvan is the moment he engages. The instant you flag onto a target you are locked into the fight you started, so the rest of the tree wants resolve and a little tenacity to let you live inside that mess. Whatever the keystone happens to be, the plan is the same, land the engage and let your team collapse onto it. Keep it simple, since the flag combo is what makes any page tick.

Jarvan IV Skill Order
The combo exists at level two. Demacian Standard goes down first, Dragon Strike follows at two so the lance can pull him to the flag for a knock up, and Cataclysm at six turns that catch into a walled arena.
Jarvan IV Abilities
His first hit on any target carries Martial Cadence, extra physical damage read off their current health, which is why his trades open so hard before the flag ever comes out. Golden Aegis is the survival tool nobody mentions, a self-shield that also slows everyone crowding around him.
Jarvan IV Base Stats
Jarvan IV Matchups
Jarvan IV eats immobile targets alive, since his combo knock-up is nearly impossible to dodge once he flags behind them. He struggles against slippery, mobile champions who flash or dash out of his ultimate walls and against poke that wears him down before he engages.
