Sion has a tank profile, so allies with CC Chain, Engage are usually the best fit. You often get the most value from partners played in Mid, ADC.
These pairings matter most around first engage timing, objective setup, and follow-up on crowd control. The page is not just naming allies: it highlights combinations that reduce execution risk for Sion.
Yasuo is one of the strongest partners highlighted on this page because the duo creates cleaner engage or follow-up sequences for Sion.
Sion usually gains the most from allies who bring CC Chain. The goal is to make the first action easier to convert into damage, tempo, or objective control.
Strong duos such as Yasuo or Orianna matter, but not more than champion mastery. Use these synergies to refine a good draft, not to replace a pick you cannot execute.
