Shipshape loadout choices
Recommendations await inspection
Arrr, best when: Apply anti-heal only when repeated healing be materially changing fights.
Arrr, best when: Locket gives nigh th' ship crewmates an immediate shield when foe burst lands together.
Arrr, best when: Shurelya's movement speed helps th' crew engage or disengage when positioning be th' problem.
Arrr, runes and summoner spells
Yuumi can follow her Bot partner through You and Me!, so this reviewed Support chart uses Heal fer th' pair and Ignite fer course pressure instead o' spending a slot on Teleport.
Replace Ignite wit' Exhaust when one diver or short burst window be th' clearer threat to Yuumi and her Bot partner.
Tell th' Bot partner that Yuumi be carrying Heal so th' pair does nay duplicate it without a reason.
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.
Keep Vex visible afore committing. Th' second Bot-course champion and nigh th' ship Jungler can change whether th' same engage 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.
Locket gives nigh th' ship crewmates an immediate shield when foe burst lands together.

Shurelya's movement speed helps th' crew engage or disengage when positioning be th' problem.

Periodically, when Yuumi strikes a champion with an attack or ability, she restores health to herself and the next ally she Attaches to. While Attached, Yuumi generates a special bond with her allies. The ally with the strongest bond enhances Yuumi's abilities while she is Attached to them.
Yuumi fires a missile, dealing damage and slowing first target hit. It deals bonus damage and an enchanced slow if it takes at least 1.35 seconds to get to its target. While on her Best Friend, the slow is always enhanced and grants bonus On-Hit damage to her ally. While Attached, the missile can be controlled with your cursor for a brief period.

Shields Yuumi and boosts Move Speed and Attack Speed. If she's attached, she passes it to her ally instead.

Wait fer reload (s) 140/120/100 · Cost 100 · Charted reach (units) 2000/2500/3000Adapt th' course
Judge th' whole course or sea chart state, nay only personal kills. Pick th' situation closest to th' present battle.
Deny space wit' yer course partner, but keep th' carry moored to th' wave instead o' roaming at every opportunity.
Move first aboard wit' an ally, establish vision and protect th' course yer crew will use to enter.
Set sail only when crewmates can follow, then change to peel if an foe reaches th' protected carry.
Hold th' trick that makes foes respect yer course and trade when both Bot-course partners be shipshape.
Recall and move on seaworthy wave timings; an unsupported roam can cost th' carry an entire wave or a dive.
Control one approach and keep enough protection fer th' foe's most likely engage.
Stay fer a crashing wave, block a dive and avoid spending th' key defensive trick on low-value poke.
Enter darkness wit' another sailor and ward th' nearest useful entrance instead o' reaching fer deep vision.
Peel first aboard and punish overextension. A blind engage rarely repairs a losing battle.
Pings, movement and prizes
Keep th' carry moored to seaworthy space. Signal peril early enough to prevent th' fight, nay after protection be already late.
Pings create a shared course; they do nay replace checking waves, vision and who can move.
'Round a minute afore Dragon, ping th' course, spend doubloons if needed and make sure Bot and Mid know whether they can move.
Walk wit' th' Jungler or another ally. Sweep one course, place useful entrance vision and ne'er face-inspect alone.
Inspect nigh th' ship waves and foe positions. Hold th' spell that either starts a reachable fight or protects yer main damage dealer.
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
Th' matchup chart be a pre-battle reference. It does nay predict th' result or alter its recommendation from changing live clash data.
