Senna is normally played Bot or Support 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 Senna Mid build
Senna is normally played Bot or Support 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.
A marksman Mid route needs a controlled attack sequence and protection from the shorter lane's burst and gank angles.

Kit reference
Senna abilities
Ability names, descriptions and numeric fields come from Riot Data Dragon. Practical reads are independently written; the current in-game tooltip remains authoritative.
What it doesWhen units die near Senna, their souls are periodically trapped by the Black Mist. Senna can attack these souls to free them, absorbing the Mist that held them in death. Mist fuels her Relic Cannon's power with increased Attack Damage, Attack Range, and Critical Strike Chance. Attacks from Senna's Relic Cannon take longer to fire, deal bonus damage, and briefly grant her a portion of her target's Move Speed.
Practical readAbsolution is an automatic part of the kit involving damage. Track when its condition is active instead of treating every fight the same way.
Q
Qability
Piercing Darkness
What it doesFrom the twin barrels of her Relic Cannon, Senna fires a unified beam of light and shadow through a target, healing allies and damaging enemies.
Practical readPiercing Darkness is a ranged cast involving protection or sustain. Respect its line or target area, and avoid spending it when the opponent can simply step away before the important exchange.
Cooldown15 secCost70/80/90/100/110Listed range600 units
Protection
The protection or sustain is part of the cast's value. Compare its timing with incoming damage rather than reading only the offensive effect.
W
Wability
Last Embrace
What it doesSenna sends forth a wave of Black Mist. If it hits an enemy it latches onto them hungrily, rooting them and everything nearby after a brief delay.
Practical readLast Embrace is part of Senna's W pattern. Read its listed effect first, then track the cooldown and condition that make the next use valuable.

Curse of the Black Mist
What it doesSenna draws the Mist she has stored in her weapon into a storm around her, embracing darkness and becoming a wraith within. Allies who enter the area are camouflaged and also appear as wraiths as the Mist shrouds them. Wraiths gain increased Move Speed, are unselectable, and hide their identities.
Practical readCurse of the Black Mist is part of Senna's E pattern. Read its listed effect first, then track the cooldown and condition that make the next use valuable.

Dawning Shadow
What it doesSenna calls upon the relic stones of fallen Sentinels, splitting her relic cannon into a holy array of shadow and light. She then fires a global beam that shields allies from harm, while damaging enemies caught in the center.
Practical readDawning Shadow is a ranged cast involving its listed effect. Respect its line or target area, and avoid spending it when the opponent can simply step away before the important exchange.

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
Senna 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.
