Movement

The cast changes position or access. Account for where the champion finishes, not only where the ability begins.

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

Kai'Sa 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.
