Shipshape loadout choices
Recommendations await inspection
Arrr, best when: Morellonomicon applies anti-heal. Buy it earlier only when healing be already deciding fights.
Arrr, best when: Arrr, zhonya's stasis can absorb a committed dive or lethal burst window.
Arrr, best when: Banshee's spell shield can protect th' first aboard fit fer th' captain's eye cast agin' ye.
Arrr, runes and summoner spells
This battle-mage chart rewards extended spell contact and enough resources to remain useful after th' first aboard rotation.
Ignite supports a short kill window; Teleport supports recall and sea chart timing; Barrier protects agin' immediate burst.
A more booty aggressive spell pair does nay replace seaworthy wave timing, river vision or an escape course.
Arrr, matchup notes
Track th' cooldown and range o' th' trick that starts their safest trade. Do nay treat this chart as a statistical counter claim.
Treat Vex as one part o' th' sea chart state. Their Jungler, nigh th' ship waves and which teammates can move determine whether th' same trade or rotation be seaworthy.
Arrr, static alternatives
These choices be nay picked from live scores. Use one only after ye identify th' stated clash problem yourself.

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.
Arrr, zhonya's stasis can absorb a committed dive or lethal burst window.

Banshee's spell shield can protect th' first aboard fit fer th' captain's eye cast agin' ye.

Judge th' whole course or sea chart state, nay only personal kills. Pick th' situation closest to th' present battle.
Push safely, then threaten vision, a side course or th' foe jungle without abandoning free farm.
Reach river first aboard wit' yer Jungler and preserve th' cooldown needed if th' foe contests.
Pressure a valuable target while respecting th' control that can end yer lead.
Trade when yer key trick and minion position favour ye; an even course does nay require a forced solo kill.
Move on a completed wave and return afore several waves be lost to th' tower.
Position fer th' champion's reliable damage or control instead o' beginning wit' th' lowest-percentage spell.
Use range, tower space and vision. Do nay contest every last aboard hit if it opens another kill.
Ping lost overboard early and take th' seaworthy course; blindly matching a stronger roam can meet defeat two positions.
Group 'round yer most dependable control and damage rather than searching alone fer a comeback.
Pings, movement and prizes
Mid can reach either side, but th' wave pays fer every move. Communicate th' foe first aboard, then move only when th' course and destination be credible.
Pings create a shared course; they do nay replace checking waves, vision and who can move.
Push, catch or communicate th' wave afore leaving so th' foe does nay gain a free move and free income.
Use On Me Way fer th' course ye be actually taking and Peril where an unseen foe may arrive.
Move through controlled vision wit' th' Jungler or another ally instead o' face-checking th' prize alone.
Decide whether ye be engaging, front-lining, flanking or protecting a carry afore th' fight begins.
Later prizes: Repeat th' same process 'round later major prizes: handle nigh th' ship income, communicate th' course, enter through vision and agree on th' fight afore committing.
Arrr, keep preparing
Th' matchup chart be a pre-battle reference. It does nay predict th' result or alter its recommendation from changing live clash data.
