Protect th' wave course

A more booty aggressive spell pair does nay replace seaworthy wave timing, river vision or an escape course.

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.
Arrr, they burst me

Zhonya's Hourglass

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

Arrr, one spell stops me

Banshee's Veil

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

Arrr, Situational AP purchase

Arrr, When should you buy anti-heal?

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, Start with the component

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, Finish when it fits the fight

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, Coordinate coverage

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, Repeated spell damage and damage over time can maintain coverage more reliably than a single hit. Match the purchase to your actual spell access, enemy sustain and the teammates who can apply the debuff.

Arrr, Will the fight last long enough?

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.

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

Manage th' wave and keep both sides o' th' sea chart visible

1
Course

Trade when yer key trick and minion position favour ye; an even course does nay require a forced solo kill.

2
Sea chart play

Move on a completed wave and return afore several waves be lost to th' tower.

3
Fights

Position fer th' champion's reliable damage or control instead o' beginning wit' th' lowest-percentage spell.

Pings, movement and prizes

Cassiopeia Mid sea chart course

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.

Ahead

Use priority to arrive first aboard, nay recklessly

Ping
Ping Foe Lost overboard when th' foe leaves, On Me Way afore entering river and Peril on th' course th' foe may use.
Arrr, stay or roam
Roam after clearing th' wave and choose th' side where crewmates can participate. Return afore several waves be lost.
Prize
Reach river wit' th' Jungler, control one entrance and preserve th' spell that stops an foe engage or secures th' first aboard target.
Even

Turn one managed wave into sea chart pressure

Ping
Use Foe Lost overboard immediately, then On Me Way only when ye be genuinely moving rather than considering it.
Arrr, stay or roam
Move after th' wave be handled. If following requires entering fog alone, ping Peril and take th' seaworthy course instead.
Prize
Lend a hand establish river vision afore th' set sail. Do nay burn th' only control spell on poke if it be needed to protect th' entrance.
Behind

Clear th' deck safely and warn both side lanes

Ping
Ping Foe Lost overboard early and repeat Peril on th' threatened side. Use Retreat if matching th' roam would expose ye to another kill.
Arrr, stay or roam
Arrr, follow through established vision or remain Mid and recover farm. A late blind follow often loses both positions.
Prize
Approach astern o' th' front line and use reliable control or range. Trade th' prize if th' crew cannae safely enter river.
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
    Handle th' wave

    Push, catch or communicate th' wave afore leaving so th' foe does nay gain a free move and free income.

  2. 2
    Signal th' course

    Use On Me Way fer th' course ye be actually taking and Peril where an unseen foe may arrive.

  3. 3
    Arrr, enter together

    Move through controlled vision wit' th' Jungler or another ally instead o' face-checking th' prize alone.

  4. 4
    Pick th' job

    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.
