Zed

Strengths

Saving energy and spell cooldowns until you use your ultimate will maximize Death Mark's damage.
Quickly double tapping Living Shadow will teleport Zed to his shadow immediately for rapid escapes.
Placing a Living Shadow before using Death Mark can give Zed a safe escape from combat.

Passive · Contempt for the Weak — Zed's basic attacks against low health targets deals bonus Magic Damage. This effect can only occur once every few seconds against the same enemy champion.
Q · Razor Shuriken — Zed and his shadows throw their shurikens. Each shuriken deals damage to every enemy hit.
W · Living Shadow — Passive: Zed gains energy whenever he and his shadows strike an enemy with the same ability. Energy can only be gained once per cast ability. Active: Zed's shadow dashes forward, remaining in place for a few seconds. Reactivating Living Shadow will cause Zed to switch positions with this shadow.
E · Shadow Slash — Zed and his Shadows slash, dealing damage to nearby enemies. Enemies hit by a Shadow's slash are slowed.
Ultimate · Death Mark — Zed becomes untargetable and dashes to an enemy champion, marking them. After 3 seconds the mark triggers, repeating a portion of all the damage Zed dealt to the target while they were marked.

A suggested 5-lane lineup built around Zed, based on hero partnerships and role synergy — not win rate.
