Sion vs Nami Matchup Summary

The Sion vs Nami matchup is a decisive matchup in League of Legends ranked play. Based on 31 recent matches analyzed, Nami wins with a 58.1% win rate compared to Sion's 41.9%, giving Nami a 16.1 percentage point advantage. Game phase dynamics play a critical role here: Sion controls the early laning stage, but Nami outscales as the game goes longer. The matchup shifts dramatically depending on game length — Sion needs to press advantages before Nami reaches their power spikes, while Nami should focus on safe farming and hitting key item breakpoints. The most significant statistical gap is in CS, where Sion leads by 1.4 CS/min — a difference that heavily influences the outcome of trades and skirmishes. Nami has a strong advantage in this matchup. Sion players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Nami overextending. Avoid prolonged trades and wait for team fights where positioning and coordination matter more. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Damage
637Sion
393Nami

9,217Nami

Utility
1.5Sion
1.4Nami
Both Sion and Nami provide similar amounts of crowd control (0.1s/min difference), meaning neither has a significant advantage in locking down opponents for ganks or team fights. Lane ganks are equally effective for both sides.
Sustain
1,780Sion
956Nami
Sion vastly out-sustains Nami, healing and mitigating 824 more damage per minute. This massive durability gap means Sion can absorb significant punishment and remain in lane while Nami is forced to recall. Building grievous wounds early is essential for Nami, and focusing on burst trade patterns rather than sustained fights is critical.

Best Sion Build Against Nami

Boots of Swiftness is the optimal boots choice against Nami, providing the mobility and stats Sion needs most in this matchup. The top-performing core items for Sion against Nami are Edge of Night, Umbral Glaive and Youmuu's Ghostblade. This combination gives Sion an effective balance of damage, survivability, and utility for the matchup. Adjustments may be needed based on team compositions and game state, but this build provides the strongest foundation for the Sion vs Nami matchup.

Nami late game win rateNami66.7%

Sion dominates the early game (first 15 minutes) with a commanding 53.9% win rate — a 7.7 percentage point lead over Nami. This lopsided early game means Sion can dictate the pace of the lane from level 1, controlling trades, wave state, and river priority.

Nami is far superior in the late game (25+ minutes), boasting a 66.7% win rate — 33.3 points above Sion. Extended games heavily favor Nami, whose kit and scaling make them a dominant force in team fights and objective control.

This matchup features a dramatic power shift: Sion must aggressively press their early advantage and close out the game before Nami reaches their scaling breakpoints. If Nami survives the laning phase without falling too far behind, the matchup flips in their favor. Dragon and Rift Herald control are pivotal — the team that secures early objectives can snowball or buy time to scale.
