By playing on the same side as Zac, he lowers their win rate by -1.1% to 50.7%. This demonstrates that there is a bad bond between Zac and Karthus that results in them performing not as well together than alone.

Karthus has a lower difficulty than Zac. That means Zac players don't need to be very careful when arranging Karthus teammates to fight alongside, as they will have to have a lower level of skill to do well with you.

When playing on the same side, you should expect to observe an overall large increase in your team’s ability to deal magical damage. When paired, these champions can blast through enemies with magic damage.

Although, by grouping Zac and Karthus together, you will not be giving your team a great deal of anti-tank damage dealing potential. Plan to include other champs on your team that helps cover this disparity in their abilities.

Regardless of your Karthus ally's skill level, you need to focus on maximizing your gold income, staying alive by avoiding foolish fights, and clearing objectives. If you do this, you will do well anyway.
