Karthus Build 26.22

C

The moment Karthus is on the map he farms toward one payoff, a global ultimate that reaches any lane and picks off low targets from anywhere on the map. On the weaker side at 49.0% and slipping, he spams a mana-cheap Q that hits twice as hard on isolated enemies and keeps casting for a few seconds after he dies. His edge is reach and map pressure, not early aggression, so farm relentlessly and treat every low-HP enemy anywhere as yours.

When Is Karthus Strongest?

This is a late-game profile, strongest with full items online, and games at this rank average around 29 minutes. Karthus wins by scaling into a late-game execute machine, so use the power window to farm safely, then start hunting cross-map kills and turning every low enemy into free damage from the fog.

Karthus Item Build

Karthus is a scaling artillery mage who farms up and then rains global damage on the entire enemy team. The build stacks ability power, mana, and haste so his blasts hit harder, his aura drains without going dry, and his ultimate can execute from anywhere on the map.

Best Karthus Runes

Dark Harvest is the go-to, and his kit feeds it perfectly. His repeated Q casts and his damage toggle keep it working, so his output climbs the longer a fight drags on. Pair it with mana and ability haste so he can keep his E toggle running and his Q flowing. It rewards exactly the sustained AoE he already brings.

Everything about Karthus improves once his damage items come together. Build toward Blackfire Torch into Shadowflame and prioritize getting there quickly. You can lose lane and still take over once the items come online. Shadowflame comes online at about the 19-minute mark, and from then his Q shreds low targets while his ult chunks the whole enemy team, so farm toward that spike above all else.

Karthus Skill Order

Wall of Pain waits until level 4 here, the first point where Karthus can slow a target rather than just chip at it. Three ranks of Lay Waste by 5 and Requiem at 6 finish the pattern.

Karthus Abilities

Defile quietly funds the whole engine, its passive handing back mana on every kill so the damage aura keeps humming. Wall of Pain does more than slow, stripping magic resist off anyone who steps through and leaving them softer for the delayed blasts to finish.

Karthus Matchups

Karthus wants to reach his items untouched, so he does well against passive lanes that let him free-farm and scale. He struggles against early aggression, dive junglers, and mobile assassins who jump on his slow, immobile body before he ever comes online.

Look out for Nocturne, Kindred, and Rammus, who can dive Karthus or blow him up before his items are online, so ward your flanks and play at range. His wall slow and post-death casting still let him trade back even when a fight looks lost. He feasts on Taliyah, Hecarim, and Rengar, where his AoE and pick-off ult find value all game, so angle fights toward them and let your damage stack up.
