Matchup notes

What changes when Vex is opposite you?

Pre-game kit comparison
Kit comparison

Respect the opponent's reliable threat

Track the cooldown and range of the ability that starts their safest trade. Do not treat this page as a statistical counter claim.

Your plan

Use the route you prepared

Treat Vex as one part of the map state. Their Jungler, nearby waves and which teammates can move determine whether the same trade or rotation is safe.

Ability reminders

Jarvan IV reminders

  • You can use the Dragon Strike / Demacian Standard combo to get out of your own Cataclysm arenas.
  • Split your basic attacks on different champions at the beginning of fights to maximize damage.
  • Use Demacian Standard as a scouting tool when worried about incoming enemies.

Adapt the plan

What to do when the game changes

Judge the whole lane or map state, not only personal kills. Choose the situation closest to the current game.

Even plan

Keep the clear moving and choose high-information plays

1
Pathing

Track opposing camps and lane states instead of forcing the first visible target.

2
Map play

Trade sides of the map when contesting would require weaker lanes to move first.

3
Fights

Save important control for the enemy who threatens your carries or objective access.

Pings, movement and objectives

Jarvan IV Jungle map plan

Link each clear to the next informed decision. Pings should tell lanes where you are pathing and whether the team is contesting or trading an objective.

Ahead

Turn tempo into controlled territory

Ping
Use On My Way before entering a lane, Assist Me before an objective and Danger when nearby lanes cannot move to an invade.
Path or gank
Gank when the lane has reach, damage and a safe exit. Do not wait beside a protected target while camps and the next objective disappear.
Objective
Establish vision with the nearest winning lane, keep Smite available and avoid chasing away from the objective after gaining control.
Even

Choose the play with the clearest information

Ping
Use On My Way early enough for the lane to prepare, Assist Me only when nearby lanes can move, and Retreat when the contest has already become late.
Path or gank
Prefer a lane with crowd control, damaged opponents or a favourable wave. A visible opponent is not automatically a usable gank.
Objective
Check Mid and Bot priority before Dragon, or Mid and Top before Herald. Set a safe entrance before beginning the objective.
Behind

Trade the map instead of forcing recovery

Ping
Ping Retreat from lost contests, Danger on likely invades and On My Way when covering a vulnerable lane or remaining camp.
Path or gank
Counter-gank or help only when allies can survive until arrival. Repeated low-chance ganks deepen the camp and level deficit.
Objective
If entry is unsafe, trade for camps, a wave, vision or the opposite objective. Keep Smite and crowd control for a contest the team can actually reach.
Objective setup

Four calls, in order

Pings create a shared plan; they do not replace checking waves, vision and who can move.

  1. 1
    Before the route

    Decide which camps lead toward the objective and ping the nearby lanes before they spend the wave or recall timing.

  2. 2
    Check priority

    Confirm which nearby lanes can move first. Do not convert an isolated objective marker into a forced fight.

  3. 3
    Control entry

    Move with a teammate, sweep one entrance and keep Smite available before committing damage to the objective.

  4. 4
    Finish or turn

    Call whether the team is finishing, fighting or leaving. Mixed decisions are more dangerous than either clear choice.

Later objectives: Repeat the same process around later major objectives: handle nearby income, communicate the route, enter through vision and agree on the fight before committing.
