Quick summary
Sun Bin is a struggling Roam Support who wants to lock down team fights with crowd control. Public guides recommend a build starting with Knowledge Gem and Heal.
Current patch decision guide
When to pick Sun Bin, when to avoid them, and how to adapt your build.
Sun Bin is a struggling Roam Support who wants to isolate high-priority targets with hard control chains. Public guide data shows a build centered on Knowledge Gem, Guardian, Boots of Tranquility, paired with Heal, used to protect the marksman, set vision, and engage on cooldown windows. Pick him when the draft lets Sun Bin reach the targets his kit is designed to threaten; avoid when the matchup denies the windows his kit needs.
Pick Sun Bin when
- The enemy team has multiple high-mobility threats that need to be locked down before they reach your backline
- Your team has the structure to use his ability to protect the marksman, set vision, and engage on cooldown windows, since Sun Bin delivers utility, vision, and timely peel for the carries.
- The enemy draft includes Kaizer and Musashi, who appear in counter data as matchups Sun Bin can pressure.
Avoid Sun Bin when
- Your team lacks the follow-up damage to convert your control windows into kills
- Your team needs a damage pick more than Sun Bin's specialty, leaving the role unfilled if you commit here.
- A stronger pick in the same role is open and the matchup does not specifically reward Sun Bin's Crowd Control.
Power spikes
Early game: focus on safe lane phase and tracking jungle pressure before Sun Bin's mid-game tools come online.
Ultimate online: Time Lapse extends control duration, making team fights snowball off a single hit
Late game: full build online, Sun Bin reaches the spike public guides describe — extended fights favor him once items are completed.
Build decisions
Default roam path
Public build references for Sun Bin recommend Knowledge Gem, Guardian, Boots of Tranquility, Guardian - Radiance, Glacial Buckler, and Boots of the Arcane, with Nightmare, Fate, and Harmony arcana. Run Heal as the battle spell. Use this as the baseline support plan before adapting to the enemy draft.
Situational item pivots
Spare options listed in build data include Dawnlight, Longnight Guardian, Spikemail, Venomous Staff, Blood Rage, and Sage's Sanctuary. Treat these as situational swaps when the default path is not enough — for example, swapping in defensive items against burst comps or penetration items against stacked armor.
Matchup logic
Versus mobility
Dashes and immunity skills bypass Sun Bin's control. Force the enemy mobility before committing Time Lapse, and aim control on stationary targets like channeling carries.
Role positioning
Sun Bin is a Roam pick whose value depends on utility, vision, and timely peel for the carries. Stick to the role plan rather than forcing fights his kit is not designed to win.
Synergies
Public synergy data lists Lady Sun and Luban No.7 as strong partners for Sun Bin. Plan engages around Lady Sun's setup window, then second-engage with Time Lapse.
Common mistakes
- Throwing Time Flux on the front-line tank instead of saving it for backline carries.
- Engaging without checking enemy summoner-spell cooldowns, which often decide whether Sun Bin's commit reaches the target alive.
- Forgetting vision while looking for picks — losing the marksman because the support roamed without setting wards is a recurring mistake.
Background
Timebender
“I want to travel into the past! And to explore the future!”
Sun Bin has always been immensely gifted, but a bit on the quiet side. During his time at Jixia Academy, even though he could manipulate the forces of machinery and even time itself, his peers mostly knew him as a shy and unassuming boy. The only one who truly recognized his talent was one of his seniors, who grew envious and proceeded to lay a deadly trap for him. Though Sun Bin survived, he lost his legs and his best friend. Using his skills in the art of machinery, he created mechanical wings that made up for the loss of his legs, and the young genius now devotes himself to studying the mysteries of mechanics and time in hopes of one day regaining his lost friend.
