The Zed Sion synergy stats shown here demonstrate the areas of his gameplay that do better (or worse) when paired with Sion, compared to his overall stats. Significant differences are areas of focus that highlight how his gameplay changes when paired with this other champion.
Overall, Zed sees a very large drop in his KDA (ratio of kills and assists to deaths) when paired with Sion. His KDA decreased from NaN to NaN. This fall shows that Sion helps Zed perform worse in ranked League of Legends rounds. Yet, the small difference demonstrates that this performance change is not very impactful.
When Zed is an ally to Sion, he observes a little increase in his full damage output. This change may signal that Sion supports by providing cover for him to dish out more damage or that his allyship also helps increase the round's duration. Similarly, when Zed is played with Sion on the same team, he usually scores many fewer killing sprees than when he plays without Sion. This is contrasting evidence that he is worse when playing with Sion.
Additionally, when Zed plays with Sion on the same team, he often takes more damage than when he plays alone. Receiving more damage could indicate that Sion does a poor job of covering Zed during teamfights.
There is no perfect ally for Zed that will always be his ideal ally. However, overall, Sion is a relatively poor teammate for Zed. By playing on the same side as Zed, he decreases their win rate by -1.5% to 46.9%.
