A melee Bot route must survive ranged access before committing. Conqueror supports the longer entry while Barrier protects the close-range damage window.

Coordinate the Support

Avoid duplicating the same defensive spell without a reason. Barrier protects the user; Heal can protect both nearby lane partners.

Cleanse is specific

Choose Cleanse only when removable crowd control is the lane or fight problem and you can use it reliably.

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

Master Yi reminders

  • If you're in a lane against ranged players, leveling up Meditate can allow you to stay in the lane longer and gain levels faster than they will.
  • Wuju Style is very strong early for last hitting minions.
  • Try using Alpha Strike on a minion in front of an enemy champion so you are placed at a safe distance at the end of the spell.

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

Prioritise farm, spacing and coordination with Support

1
Lane

Match the opposing carry's income and trade when both lane partners can participate.

2
Map play

Finish the wave before rotating unless the fight is immediate and clearly reachable.

3
Fights

Stand behind allied control and build damage on reachable targets before stepping toward the back line.

Pings, movement and objectives

Master Yi Bot map plan

Protect income and coordinate with Support. Your movement should follow the wave, while your pings make target choice and danger clear before the fight begins.

Ahead

Carry the lead into the next safe fight

Ping
Use Target on the reachable opponent, Danger when Support or Jungle is too far away, and On My Way after the wave is secured.
Farm or rotate
Finish the wave, recall on the item timing and rotate with protection. Do not cross river alone to save a few seconds.
Objective
Attack from the safe side of the objective and keep damaging the nearest reachable threat. Preserving the shutdown matters more than chasing.
Even

Build the item timing and move together

Ping
Use Target to align with Support, Enemy Missing when either Bot opponent leaves and Danger if an engage begins outside your safe range.
Farm or rotate
Rotate after the wave or when the objective fight is immediate and reachable. Communicate if staying for the wave is the safer call.
Objective
Enter behind vision and allied control. Keep a route away from the enemy engage before starting sustained damage.
Behind

Shorten exposure and recover guaranteed gold

Ping
Use Retreat before Support or Jungle forces a fight you cannot damage, and Enemy Missing as soon as the winning Bot lane leaves.
Farm or rotate
Avoid being first into river. Move with Support after the safe wave, or trade an unsafe objective for protected farm.
Objective
Stand beside peel and attack whoever enters safe range. Do not cross enemy control to reach the opposing carry.
Objective setup

Four calls, in order

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

  1. 1
    Secure the wave

    Finish safe farm and communicate the recall or move before the objective setup begins.

  2. 2
    Enter protected

    Walk with Support or another ally and choose the side where enemy engage cannot reach you first.

  3. 3
    Set attack space

    Keep an exit route and identify the nearest target you can damage without crossing enemy control.

  4. 4
    Stay alive

    Continue useful damage without chasing away from the objective or donating a shutdown.

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.
