Coordinate th' Bot pair

Respect th' foe's reliable threat

Track th' cooldown and range o' th' trick that starts their safest trade. Do nay treat this chart as a statistical counter claim.

Yer course

Use th' course ye prepared

Keep Vex visible afore committing. Th' second Bot-course champion and nigh th' ship Jungler can change whether th' same engage be seaworthy.

Trick reminders

Cassiopeia reminders

  • Use Twin Fang on poisoned stationary targets like monsters and units stunned by her Petrifying Gaze fer maximum damage.
  • Lead yer foe when targeting wit' Noxious Blast to ensure th' hit.

Arrr, static alternatives

Compare th' problem afore changing th' course

These choices be nay picked from live scores. Use one only after ye identify th' stated clash problem yourself.

Arrr, Only when enemy healing is deciding fights

Oblivion Orb

Arrr, 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.

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

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

1
Course

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

2
Sea chart play

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

3
Fights

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

Pings, movement and prizes

Cassiopeia 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. 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. 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. 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. 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.

Arrr, keep preparing

Use th' champion chart or choose another foe

Th' matchup chart be a pre-battle reference. It does nay predict th' result or alter its recommendation from changing live clash data.
