Itemization vs Sima Yi (Assassin):

Tanks/Warriors:
• First big item should be defensive stats matching Sima Yi's primary damage type (armor).
• Immortal Robe or Blade of Resilience for anti-burst survivability.
• If Sima Yi has sustain/lifesteal → build anti-heal immediately.

Damage Dealers:
• Defensive item 3rd or 4th. Surviving Sima Yi's burst is more important than a 6th damage item.
• Purify can cleanse Sima Yi's CC chain — often saves more lives than Flash.

Core strategy when laning against Sima Yi:

• Levels 1-3 are your best window. Most heroes are weakest before their ultimate. Trade aggressively early.
• Track cooldowns. Bait out Sima Yi's key ability, then punish during the cooldown window.
• Control wave position. Don't mindlessly push — a frozen wave near your tower sets up easy jungle ganks.
• Ping your jungler. Let them know when Sima Yi's Flash or escape is on cooldown for guaranteed kills.
• Vision is life. Ward the river brush. If you don't see the enemy jungler, assume they're coming for you.

How to handle Sima Yi in teamfights:

• Deny comfortable positioning. Control vision around flank routes so Sima Yi can't find an easy angle.
• Save hard CC for Sima Yi specifically. Don't waste stuns, knockups, or suppression on the enemy tank — Sima Yi is the real threat.
• The moment Sima Yi uses their mobility/escape cooldown is your kill window. Call for immediate focus fire.
• If Sima Yi hasn't shown yet, don't hard commit. Wait for them to reveal before fully engaging.
• Spread your formation. Clumping together lets Sima Yi hit everyone with AoE. Keep some distance between teammates.

Ban Phase:
• If your team lacks reliable ways to shut down Sima Yi and the enemy might pick it — ban it.
• Sima Yi's ban priority increases at higher ranks where players can maximize the champion's potential.

Pick Phase:
• Don't first-pick Sima Yi. It invites counter-picks.
• If the enemy has already locked a known Sima Yi counter (e.g. Alessio, Arli, Lady Zhen), seriously reconsider picking Sima Yi.
• Sima Yi shines with specific team compositions. Communicate with your team about playstyle before locking in.
