Recommendations await inspection
Arrr, best when: Morellonomicon applies anti-heal. Move it earlier only when repeated healing be already deciding fights.
Arrr, best when: Arrr, zhonya's stasis can absorb a committed dive after Lux has used her binding or shield.
Arrr, best when: Banshee's spell shield can protect Lux from th' first aboard decisive hostile trick.
Recommendations await inspection
Arrr, runes and summoner spells
Use controlled poke and preserve th' cooldown that makes th' next aboard catch seaworthy.
Inspect which defensive spell th' Bot partner picked afore duplicating Heal, Barrier or Exhaust.
Exhaust answers a committed damage dealer; Ignite adds pressure and anti-heal; Heal protects both nigh th' ship partners.
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 after Lux has used her binding or shield.

Banshee's spell shield can protect Lux from th' first aboard decisive hostile trick.
Arrr, Situational AP purchase
Arrr, Buy healing reduction when enemy healing or regeneration is deciding fights and you can keep damaging the relevant target. Grievous Wounds reduces healing; it does not reduce shields, magic damage or crowd control.
Arrr, Oblivion Orb can provide healing reduction without immediately paying for a completed Morellonomicon. Fit the component around your core damage, mana and survival needs; check the current queue's item tooltip.
Arrr, Complete Morellonomicon when its stats and slot efficiency suit your build. Do not treat it as a mandatory first item just because your champion deals magic damage.
Arrr, Multiple Grievous Wounds sources do not add their percentages together. Another reliable applier may cover the same target, but you may still need your own source for a separate fight or target.
Arrr, Playing Lux: Arrr, Prioritize a reliable burst kill, mana or survival when that is the real problem. Consider anti-heal for healing targets your damaging spells can reach; W does not apply it. As Support, check allied coverage before spending limited gold or delaying utility.
Arrr, If you die before dealing damage, you apply no healing reduction. If your target dies before healing, there is little healing to prevent. The debuff applies on qualifying damage immediately; it does not need to build up. It remains briefly after your last hit, so teammates can benefit even after you disengage.
Arrr, Only healing during the active debuff counts. For example, 40% reduction prevents 80 of a 200-point heal, or 400 of a 1,000-point heal, before other modifiers. Compare that with the damage, penetration or survival you delayed; neither example guarantees a kill. Healing after the debuff expires is unaffected.
Arrr, See the Arrr, oblivion Orb and Arrr, Morellonomicon Arrr, references for current effects and queue availability. These are situational decisions, not a measured best-build claim.
Arrr, kit reference
Trick names, descriptions and numeric fields come from Riot Data Dragon. Practical reads be independently written; th' present in-battle tooltip remains authoritative.

Arrr, what it doesEnglishLux's damaging spells charge the target with energy for a few seconds. Lux's next attack ignites the energy, dealing bonus magic damage (depending on Lux's level) to the target.

Arrr, what it doesEnglishLux releases a sphere of light that binds and deals damage to up to two enemy units.

Arrr, what it doesEnglishLux throws her wand and bends the light around any friendly target it touches, protecting them from enemy damage.

Arrr, what it doesEnglishFires an anomaly of twisted light to an area, which slows nearby enemies. Lux can detonate it to damage enemies in the area of effect.

Arrr, what it doesEnglishAfter gathering energy, Lux fires a beam of light that deals damage to all targets in the area. In addition, triggers Lux's passive ability and refreshes the Illumination debuff duration.
Adapt 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
Use range to earn space, then keep enough mana and cooldowns fer th' prize entrance.
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.
Use th' chart
Compare a specific foe, return to th' champion overview, or choose another champion without losing th' queue distinction.
