According to the current data for Patch 16.2.1, there are no specific champions listed as counters for Karthus Bot. While he maintains a 52.3% win rate, the limited 1.1% pick rate means statistical counter data is currently unavailable. Players should focus on general mage-countering strategies until more specific data is recorded.

There is currently no favorable matchup data available for Karthus Bot in the Patch 16.2.1 dataset. As a Mage with a 52.3% win rate, he is performing well overall in the A-tier category. However, we cannot identify specific champions he statistically dominates at this time.

The available statistics for Patch 16.2.1 do not provide specific data on Karthus's worst matchups in the bottom lane. Since no counter data is listed, his performance seems stable across the board for his 1.1% pick rate. You should anticipate standard bot lane threats that can dodge his skill shots.

Data regarding Karthus's best matchups is currently unavailable for this patch. While his A-tier status and 52.3% win rate suggest he is a strong pick, the specific champions he beats most often are not recorded in the provided statistics. He likely excels against opponents who cannot easily escape his area of effect damage.

When facing Karthus Bot, focus on dodging his Lay Waste and managing your positioning to avoid taking doubled isolation damage. Since he is an immobile Mage with a 7/10 difficulty rating, capitalize on his reliance on landing skill shots. Keeping the wave in a favorable position can help you avoid being whittled down by his long-range poke.

There is no lane counter data available to specify which champions achieve the best gold or CS differentials at 15 minutes. Generally, high-mobility champions or those with strong early-game pressure might find success against his mage playstyle. Without specific GD@15 data, it is best to rely on standard lane mechanics and dodging skill shots.

With a 52.3% win rate and an A-tier ranking, Karthus Bot is a formidable opponent that is not easily countered by the current field. The lack of documented counters in the data suggests that many players are struggling to find consistent ways to suppress his impact. His high win rate indicates he is a very effective choice in the current meta.

Because there are no statistically confirmed counters in the Patch 16.2.1 data, you should pick champions you are comfortable with that can effectively dodge skill shots. Champions with high sustain or high burst are typically good choices against immobile mages like Karthus. Focus on champions that can punish his lack of mobility and high mechanical difficulty.

Although specific champion names are not provided in the data, Karthus generally loses to those who can disrupt his positioning or evade his consistent damage. His difficulty rating of 7/10 implies that opponents who can exploit his mechanical requirements will have the upper hand. Champions that can survive his ultimate or outrange his poke are likely to perform better.

Patch 16.2.1 did not include any champion changes for Karthus, so his matchup dynamics remain stable from the previous cycle. His win rate of 52.3% and A-tier status reflect his current power level in a meta where he received no direct buffs or nerfs. Players can expect his performance to be consistent with how he played prior to this patch.
