Role fit
Mid · Kennen
Kennen is normally played Top and does not currently have a reviewed Mid route. Mid usually needs solo-lane safety plus wave control, roaming or reliable burst pressure. Treat this as a deliberate experiment, not a standard recommendation.
These patches track recommendation review, build validation and item lookup separately. Updating item data does not complete a build review.

Unreviewed route
No reviewed Kennen Mid build
Kennen is normally played Top and does not currently have a reviewed Mid route. Mid usually needs solo-lane safety plus wave control, roaming or reliable burst pressure. Treat this as a deliberate experiment, not a standard recommendation.
A different lane's items are not relabelled as correct. Role income, map access and starting rules can change the whole purchase order.
Control Mid range, mana and wave timing before committing to a longer exchange or roam.

Choose pressure or recovery
Ignite supports a short kill window; Teleport supports recall and map timing; Barrier protects against immediate burst.
Protect the wave plan
A more aggressive spell pair does not replace safe wave timing, river vision or an escape route.

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
Kennen reminders
You can stun your opponents by inflicting 3 Marks of the Storm upon them.
Lightning Rush can be used to initiate fights with its Energy return component, allowing him to use other abilities afterward.
You can land an initial Mark of the Storm debuff on an opponent with Thundering Shuriken, and then add to it with Electrical Surge.
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.

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.
Ahead plan
Use wave priority before looking for another play
1
Lane
Push safely, then threaten vision, a side lane or the enemy jungle without abandoning free farm.
2
Map play
Reach river first with your Jungler and preserve the cooldown needed if the opponent contests.
3
Fights
Pressure a valuable target while respecting the control that can end your lead.
Even plan
Manage the wave and keep both sides of the map visible
1
Lane
Trade when your key ability and minion position favour you; an even lane does not require a forced solo kill.
2
Map play
Move on a completed wave and return before several waves are lost to the tower.
3
Fights
Position for the champion's reliable damage or control instead of beginning with the lowest-percentage spell.
Behind plan
Clear safely and make the opponent expose themselves
1
Lane
Use range, tower space and vision. Do not contest every last hit if it opens another kill.
2
Map play
Ping missing early and take the safe route; blindly matching a stronger roam can lose two positions.
3
Fights
Group around your most dependable control and damage rather than searching alone for a comeback.
Pings, movement and objectives
Kennen Mid map plan
Mid can reach either side, but the wave pays for every move. Communicate the opponent first, then move only when the route and destination are credible.
Ahead
Use priority to arrive first, not recklessly
Ping
Ping Enemy Missing when the opponent leaves, On My Way before entering river and Danger on the route the opponent may use.
Stay or roam
Roam after clearing the wave and choose the side where allies can participate. Return before several waves are lost.
Objective
Reach river with the Jungler, control one entrance and preserve the spell that stops an enemy engage or secures the first target.
Even
Turn one managed wave into map pressure
Ping
Use Enemy Missing immediately, then On My Way only when you are genuinely moving rather than considering it.
Stay or roam
Move after the wave is handled. If following requires entering fog alone, ping Danger and take the safe route instead.
Objective
Help establish river vision before the start. Do not burn the only control spell on poke if it is needed to protect the entrance.
Behind
Clear safely and warn both side lanes
Ping
Ping Enemy Missing early and repeat Danger on the threatened side. Use Retreat if matching the roam would expose you to another kill.
Stay or roam
Follow through established vision or remain Mid and recover farm. A late blind follow often loses both positions.
Objective
Approach behind the front line and use reliable control or range. Trade the objective if the team cannot safely enter river.
Objective setup
Four calls, in order
Pings create a shared plan; they do not replace checking waves, vision and who can move.
1
Handle the wave
Push, catch or communicate the wave before leaving so the opponent does not gain a free move and free income.
2
Signal the route
Use On My Way for the route you are actually taking and Danger where an unseen opponent may arrive.
3
Enter together
Move through controlled vision with the Jungler or another ally instead of face-checking the objective alone.
4
Choose the job
Decide whether you are engaging, front-lining, flanking or protecting a carry before the fight begins.
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.
