Zed requires high mechanical skill; focus on early farming and item scaling to become a powerful late-game assassin.
Being squishy, Zed is vulnerable to CC; consider a Conqueror bruiser build for beginners or to enhance survivability.
Once itemized, Zed can threaten squishies and even bruisers. However, avoid Zed jungle, as it is generally ineffective.
