Provides Smite progression and the defensive Jungle companion.

This item is part of the most-supported coherent core in the frozen prior-patch public role snapshot. Treat the sample as context, then adjust only for a clearly identified matchup problem.

This is the most-supported Boots choice in the frozen prior-patch public role snapshot; change it when the opposing damage or crowd control calls for a different defence.

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: Black Cleaver shreds armour during extended fights.
Runes and summoner spells
Reach the fight with control available and absorb the first response.
Smite is part of Jungle companion progression and objective security. The movement or combat spell beside it is the adjustable slot.
Ghost can fit sustained access; Flash can fit one immediate reposition. Use the champion's route and intended fights to choose.
Matchup notes
Durability and forced targeting are useful answers to a champion relying on a decisive entry.
Mid to lateControl and protection become clearer once teams group around objectives and carries need a front line.
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.

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 (s) 100/85/70 · Cost 80Adapt the plan
Judge the whole lane or map state, not only personal kills. Choose the situation closest to the current game.
Take efficient camps between plays so a lead does not disappear into repeated waiting.
Use lane priority before invading or starting an objective, and leave when nearby lanes cannot move.
Enter through controlled vision and keep a route out; a winning Jungler still loses a shutdown when isolated.
Track opposing camps and lane states instead of forcing the first visible target.
Trade sides of the map when contesting would require weaker lanes to move first.
Save important control for the enemy who threatens your carries or objective access.
Path through known territory and help lanes only when the opponent is genuinely vulnerable.
Cross-map rather than arriving late to a lost objective, then restore defensive vision with an ally.
Play around the strongest teammate and make the enemy commit into your control.
Pings, movement and objectives
Link each clear to the next informed decision. Pings should tell lanes where you are pathing and whether the team is contesting or trading an objective.
Pings create a shared plan; they do not replace checking waves, vision and who can move.
Decide which camps lead toward the objective and ping the nearby lanes before they spend the wave or recall timing.
Confirm which nearby lanes can move first. Do not convert an isolated objective marker into a forced fight.
Move with a teammate, sweep one entrance and keep Smite available before committing damage to the objective.
Call whether the team is finishing, fighting or leaving. Mixed decisions are more dangerous than either clear choice.
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.
