Exhaust answers a committed damage dealer; Ignite adds pressure and anti-heal; Heal protects both nearby partners.

Matchup notes

What changes when Olaf is opposite you?

Pre-game kit comparison
Strategic interaction

Reset the engagement

Disengage and movement control can protect a carry after a tank commits forward.

Mid to late

Control and protection become clearer once teams group around objectives and carries need a front line.

Your plan

Use the route you prepared

Keep Vex visible before committing. The second Bot-lane champion and nearby Jungler can change whether the same engage is safe.

Ability reminders

Janna reminders

  • Eye of the Storm can be used on allied turrets.
  • Quickly firing a Howling Gale without the charge up can be used to heavily disable the other team.
  • Timing Janna's ultimate can push enemies away from a wounded ally or even separate enemies.
Ability reminders

Against Olaf

  • Olaf becomes more dangerous the lower life he is. Save your disables to finish him off.
  • Preventing Olaf from reaching his axe will minimize the amount of harassment he can cause in the laning phase.
  • Olaf has reduced defenses from damage during Ragnarok, despite being immune to disables. If you can't escape from Olaf during Ragnarok, try focusing your damage on him with your teammates.

Static alternatives

Compare the problem before changing the plan

These choices are not selected from live scores. Use one only after you identify the stated match problem yourself.

Only when enemy healing is deciding fights

Oblivion Orb

Oblivion Orb supplies healing reduction without committing to a completed Morellonomicon. Skip both when healing is not the problem or an ally already covers your target reliably. Healing reduction does not reduce shields.

Conditional component, not a core item. Complete Morellonomicon only when its stats and slot efficiency justify delaying another purchase.
Team gets burst

Locket of the Iron Solari

Locket gives nearby allies an immediate shield when enemy burst lands together.

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

Balance lane pressure with protection for the carry

1
Lane

Hold the ability that makes opponents respect your lane and trade when both Bot-lane partners are ready.

2
Map play

Recall and move on safe wave timings; an unsupported roam can cost the carry an entire wave or a dive.

3
Fights

Control one approach and keep enough protection for the enemy's most likely engage.

Pings, movement and objectives

Janna Support map plan

Keep the carry connected to safe space. Signal danger early enough to prevent the fight, not after protection is already late.

Ahead

Make the lead open the map

Ping
Use On My Way before changing angle, then Assist Me on Dragon after Bot is safe to move. Use Danger if the carry starts following through an unsafe route.
Map movement
Roam after a pushed wave, shared recall or when the carry can collect safely. Deep wards still require the Jungler or another nearby ally.
Objective
Arrive early, clear the enemy entrance and hold the key engage or peel spell. Do not chase away from Dragon and hand the opponent a free route back in.
Even

Create one clear numbers advantage

Ping
Use On My Way before an engage or roam, Enemy Missing as soon as a lane opponent disappears, and Danger when your carry cannot follow.
Map movement
Leave only on a safe wave or recall timing. If the carry would lose a full wave or face a dive, stay Bot and communicate that you are not moving.
Objective
Help Bot finish the wave, then enter river with the Jungler. Set vision before starting and avoid turning an even objective into an unseen gamble.
Behind

Stop the next loss before seeking a play

Ping
Use Retreat or Danger before an ally enters darkness, Enemy Missing immediately, and Assist Me when you need company to restore defensive vision.
Map movement
Do not abandon a crashing wave or vulnerable carry. Move after the wave is stable and use the nearest safe ward line rather than forcing deep vision.
Objective
If your team cannot enter river safely, ping Retreat and trade for farm, vision or another map resource. Contest only after creating a safe route together.
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 move

    Around a minute before Dragon, ping the plan, spend gold if needed and make sure Bot and Mid know whether they can move.

  2. 2
    Enter together

    Walk with the Jungler or another ally. Sweep one route, place useful entrance vision and never face-check alone.

  3. 3
    Before starting

    Check nearby waves and enemy positions. Hold the spell that either starts a reachable fight or protects your main damage dealer.

  4. 4
    During the contest

    Keep enemies away from the safe entrance, mark the reachable threat and avoid chasing so far that Dragon is left unprotected.

Later objectives: Use the same pattern for Rift Herald or Baron: communicate first, move through controlled vision with an ally, then choose engage or peel before the fight begins.
