What the Rift Lab holds on this champion: the kit as Riot publishes it, the build the lab reviewed, and the matchups it has documented. Anything the dataset does not record is left out rather than filled in.
Riot's own text for each slot, in the order the champion learns them.
Zilean stores time as Experience and can grant it to his allies. Zilean can impart this Experience on the nearest allied champion when he has enough to complete their next level up. Zilean receives as much Experience as he gives.
Tosses a bomb to target area that sticks to units that come near it, prioritizing champions and units already carrying a bomb. When it detonates it deals magic damage to the target and nearby enemies. If a Time Bomb is detonated early by another Time Bomb, it also stuns enemies. The Time Bomb can be recharged 2 times.
Makes time flow faster for himself, applying Fleeting Time to himself and gaining a damage absorbing shield. Zilean also grants Fleeting Time and identical shield to his nearest ally champion. Fleeting Time increases projectile speeds and grants move speed. Fleeting Time also increases Zilean’s ability haste.
Creates a time-bending force field at target location. Within the force field enemy champions and projectiles are slowed.
Places a protective time rune on Zilean or an allied champion. If the rune bearer takes lethal damage during this time, they teleport back in time and become untargetable before they are revived and healed. If the rune bearer does not trigger the rune's revival effect, a part of Chronoshift's cooldown will be refunded.
The reviewed purchase order and rune page for this champion. Every entry that has a page of its own is linked to it; an item the catalogue holds no page for is printed as a name rather than pointed at a page that does not exist.
One slot, changed when the enemy team changes the problem. These are answers, not automatic purchases.
Ability text and the in-game title follow Riot's official Wild Rift champion pages. The tier letter is the external snapshot shown on the tier list, and the build is the Nexus reviewed snapshot — neither is a win rate.
In the matchup data documented in Rift Lab, these are the harder matchups for Zilean: Blitzcrank (Support), Pyke (Support), Leona (Support), Nautilus (Support), Brand (Mid). This is a documented matchup list, not a win rate: TheNexus does not publish win-rate or pick-rate figures it cannot source.
Riot's ability text for Zilean describes crowd control (a stun, root, knock-up, pull or similar) in TIME BOMB (ability 1); a dash, leap or blink in CHRONOSHIFT (ultimate); a shield in TWISTED TIMEFLOW (ability 2). Plan around those abilities before a trade or a fight. These notes are keyword matches over the ability text only, not a rating of how strong Zilean is, so read the full descriptions on this page.
The Nexus-reviewed core build for Zilean, in purchase order: Ardent Censer then Harmonic Echo then Redemption then Ionian Boots of Lucidity. Runes: Aery, Font of Life, Bone Plating, Revitalize, Transcendence. Situational swaps: against enemy crowd control: Mikael's Blessing. This is a reviewed snapshot (patch 7.2b), not a build ranked by win rate.
Zilean is a Support and Mage by Riot's classification and is played in Support. Riot rates the difficulty Medium. On our tier-list snapshot (patch 7.2b) it shows S tier from its external source, which is a snapshot letter and not a TheNexus win rate.
Every answer here is built from Rift Lab data and Riot's own ability text. Where the data is missing we say so instead of guessing.
