Role fit
Zac has a reviewed secondary role here. It is less common than the primary roles, but it has a recognisable role-specific plan.
These patches track recommendation review, build validation and item lookup separately. Updating item data does not complete a build review.

Complete build choices
Recommendation review pending
Best when: Chempunk Chainsword adds anti-heal without abandoning attack damage and health.
Best when: Death's Dance delays physical damage so takedowns can stabilise the fight.
Best when: Kaenic Rookern is a defensive answer when repeated magic damage is the real problem.
Best when: Black Cleaver shreds armour during extended fights.
Runes and summoner spells
Take measured lane trades, scale durability and keep a route back to the map.
Teleport preserves recalls and side-lane access. Ignite is a deliberate pressure trade-off, not a universal upgrade.
Keep the defensive secondary runes when repeated poke or one committed trade can decide the lane.
Matchup notes
Track the cooldown and range of the ability that starts their safest trade. Do not treat this page as a statistical counter claim.
Treat Vex as one part of the map state. Their Jungler, nearby waves and which teammates can move determine whether the same trade or rotation is safe.
Static alternatives
These choices are not selected from live scores. Use one only after you identify the stated match problem yourself.

Chempunk Chainsword adds anti-heal without abandoning attack damage and health.

Death's Dance delays physical damage so takedowns can stabilise the fight.

Kaenic Rookern is a defensive answer when repeated magic damage is the real problem.

Black Cleaver shreds armour during extended fights.

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

Cooldown 140/120/100 · Cost 100 · Listed range 2000/2500/3000Adapt the plan
Judge the whole lane or map state, not only personal kills. Choose the situation closest to the current game.
Hold a favourable wave, pressure the enemy away from farm and keep enough vision to survive the second opponent.
Push before moving to an objective; arrive through a known route rather than giving up the wave and your shutdown.
Use the lead to occupy space for the team. Do not chase through the entire enemy formation for one target.
Keep health and minions balanced so one poor trade does not decide the lane.
Move after the wave is handled and communicate if the opposing Top laner leaves first.
Choose between front-line duty, side pressure and carry access according to the champion kit.
Farm near safety, avoid repeating the losing trade and ask for help only when the wave creates a realistic window.
Do not follow a stronger opponent through unseen river. Signal the move and recover guaranteed resources.
Contribute control or pressure to the nearest safe target instead of trying to repair the score alone.
Pings, movement and objectives
Manage the long lane before leaving it. A useful move begins with a handled wave, a visible route and a teammate who knows you are coming.
Pings create a shared plan; they do not replace checking waves, vision and who can move.
Push, catch or communicate the wave before leaving so the opponent does not gain a free move and free income.
Use On My Way for the route you are actually taking and Danger where an unseen opponent may arrive.
Move through controlled vision with the Jungler or another ally instead of face-checking the objective alone.
Decide whether you are engaging, front-lining, flanking or protecting a carry before the fight begins.
Later objectives: Repeat the same process around later major objectives: handle nearby income, communicate the route, enter through vision and agree on the fight before committing.
