Senna tricks

Trick names, descriptions and numeric fields come from Riot Data Dragon. Practical reads be independently written; th' present in-battle tooltip remains authoritative.

Tricks Data Dragon 16.20.1Cooldown / Cost / Range Data Dragon 16.20.1

Passive

Absolution

Arrr, what it doesEnglishWhen 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.

Arrr, practical readAbsolution be an automatic part o' th' kit involving damage. Track when its condition be active instead o' treating every fight th' same way.

Q trick

Piercing Darkness

Arrr, what it doesEnglishFrom the twin barrels of her Relic Cannon, Senna fires a unified beam of light and shadow through a target, healing allies and damaging enemies.

Arrr, practical readPiercing Darkness be a ranged cast involving protection or sustain. Respect its line or target area, and avoid spending it when th' foe can simply step astern afore th' fit fer th' captain's eye exchange.

CooldownArrr, 15 secCost70/80/90/100/110Arrr, listed rangeArrr, 600 units

Protection

Th' protection or sustain be part o' th' cast's value. Compare its timing wit' incoming damage rather than reading only th' offensive effect.

W trick

Last Embrace

Arrr, what it doesEnglishSenna 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.

Arrr, practical readLast Embrace be part o' Senna's W pattern. Read its listed effect first aboard, then track th' cooldown and condition that make th' next aboard use valuable.

CooldownArrr, 11 secCost50/55/60/65/70Arrr, listed rangeArrr, 1250 units

E trick

Curse of the Black Mist

Arrr, what it doesEnglishSenna 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.

Arrr, practical readCurse o' th' Black Mist be part o' Senna's E pattern. Read its listed effect first aboard, then track th' cooldown and condition that make th' next aboard use valuable.

CooldownArrr, 26/24.5/23/21.5/20 secCost70Arrr, listed rangeArrr, 400 units

Ultimate

Dawning Shadow

Arrr, what it doesEnglishSenna 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.

Arrr, practical readDawning Shadow be a ranged cast involving its listed effect. Respect its line or target area, and avoid spending it when th' foe can simply step astern afore th' fit fer th' captain's eye exchange.

CooldownArrr, 140/120/100 secCost100Arrr, listed rangeArrr, 25000 units

Protection

Th' protection or sustain be part o' th' cast's value. Compare its timing wit' incoming damage rather than reading only th' offensive effect.

Adapt th' course

What to do when th' battle changes

Judge th' whole course or sea chart state, nay only personal kills. Pick th' situation closest to th' present battle.

Even course

Balance course pressure wit' protection fer th' carry

Course

Hold th' trick that makes foes respect yer course and trade when both Bot-course partners be shipshape.

Sea chart play

Recall and move on seaworthy wave timings; an unsupported roam can cost th' carry an entire wave or a dive.

Fights

Control one approach and keep enough protection fer th' foe's most likely engage.

Pings, movement and prizes

Senna Support sea chart course

Turn ship's intelligence into a shared decision. Move wit' an ally and preserve th' tool that makes th' next aboard fight seaworthy.

Ahead

Make th' lead open th' sea chart

Ping: Use On Me Way afore changing angle, then Assist Me on Dragon after Bot be seaworthy to move. Use Peril if th' carry starts following through an unsafe course.
Sea chart movement: Roam after a pushed wave, shared recall or when th' carry can collect safely. Deep wards still require th' Jungler or another nigh th' ship ally.
Prize: Arrive early, clear th' deck th' foe entrance and hold th' key engage or peel spell. Do nay chase astern from Dragon and hand th' foe a free course back aboard in.

Even

Create one clear th' deck numbers advantage

Ping: Use On Me Way afore an engage or roam, Foe Lost overboard as soon as a course foe disappears, and Peril when yer carry cannae follow.
Sea chart movement: Leave only on a seaworthy wave or recall timing. If th' carry would meet defeat a full wave or face a dive, stay Bot and communicate that ye be nay moving.
Prize: Lend a hand Bot finish th' wave, then enter river wit' th' Jungler. Set vision afore starting and avoid turning an even prize into an unseen gamble.

Behind

Stop th' next aboard defeat afore seeking a play

Ping: Use Retreat or Peril afore an ally enters darkness, Foe Lost overboard immediately, and Assist Me when ye need company to restore defensive vision.
Sea chart movement: Do nay abandon a crashing wave or vulnerable carry. Move after th' wave be stable and use th' nearest seaworthy ward line rather than forcing deep vision.
Prize: If yer crew cannae enter river safely, ping Retreat and trade fer farm, vision or another sea chart resource. Contest only after creating a seaworthy course together.

Prize setup

Arrr, four calls, in order

Pings create a shared course; they do nay replace checking waves, vision and who can move.

1
Afore th' move
'Round a minute afore Dragon, ping th' course, spend doubloons if needed and make sure Bot and Mid know whether they can move.
2
Arrr, enter together
Walk wit' th' Jungler or another ally. Sweep one course, place useful entrance vision and ne'er face-inspect alone.
3
Afore starting
Inspect nigh th' ship waves and foe positions. Hold th' spell that either starts a reachable fight or protects yer main damage dealer.
4
During th' contest
Keep enemies astern from th' seaworthy entrance, mark th' reachable threat and avoid chasing so far across th' waters that Dragon be left unprotected.

Later prizes: Use th' same pattern fer Rift Herald or Baron: communicate first aboard, move through controlled vision wit' an ally, then choose engage or peel afore th' fight begins.
