Yi Sun-shin MLBB Guide: Two Weapons, One Tempo (Season 42)

Why he's feared (and loved)

You're at a third of your health, hiding in the river bush, recall bar nearly full — and the entire map lights up. Every bush, every camp, your jungler mid-buff: all visible, because somewhere an admiral just called his fleet. Three seconds later a turtle ship rams your tank at the Turtle pit, cannons walk across the choke, and the man himself slides through your front line swapping longbow for glaive mid-fight.

That's Yi Sun-shin, the Paenlong Legend — Mobile Legends' only Assassin/Marksman, modelled on the real Korean admiral Yi Sun-sin, and built around one idea: distance is a weapon. Far away, he shoots. Close up, he cuts. And every time he crosses that line, his next two attacks hit harder and faster. Good Yi Sun-shin players don't have a favourite weapon — they have a favourite *tempo*: swap, cash two enhanced hits, swap again — while the enemy team works out which him they're losing to.

One honesty note before the fan mail: if you learned him from older guides, unlearn two things. There is no bleed anywhere in his current kit, and Skill 1 hasn't been called "One-wave Sweep" in a long time. The modern admiral is a swap engine with a global reveal, not a bleed stacker — and he's more interesting for it.

Season 42 viability: the honest read

Patch 2.2.16 (16 September 2026) did touch him, and Moonton said why: "Yi Sun-shin's overall mobility was too high." The nerf is one line — Traceless cooldown 12–7s → 12–9s — so late-game dashes return meaningfully slower. Fandom's hero page still prints the old 12–7s table; the patch note wins. VCGamers' patch roundup lists the same nerf. The trackers, checked 21 October 2026:

MLBBHub (daily refresh): 49.8% win rate, 1.1% pick, 4.6% ban — highest pick rate of any assassin left in my guide queue; its builds page files him Tier B.
MLBBDex (tier list, patch 2.2.16): 49.7% win rate, 1.1% pick, 4.3% ban — and a fascinating note: the most-played jungler in Mythical Glory, especially effective in short games, win rate back to average after the twelfth minute.
MLBBGuides (snapshot updated 29 September 2026): A tier at 51.89% win, 1.73% pick, 13.27% ban — noticeably hotter than the daily pair; the site itself calls its rates directional, so I read it as the optimist at the table.
MLCounter (matchup snapshot, June 2026 — older, small samples): worst listed matchups Alucard (he wins 42%) and Lancelot (43%); best is Fanny, at 58%.

The chorus: 49.7–49.8% on the sources that refresh daily — a coin flip tilted slightly against him in average hands, played constantly at the highest bracket anyway. That gap is the hero: the spreadsheet measures everyone, including players standing in one stance spamming basics. One flag: MLBBHub's write-up mentions a "shorter ship window" after 2.2.16, but the official notes list no Mountain Shocker change and Fandom still prints a 15-second ship — unconfirmed. Patch 2.2.16a (14 October) documents no Yi Sun-shin change either (Kalea buff; Aulus, Hirara, Eudora, Rafaela nerfs); with no Fandom page for it, contrary claims stay unconfirmed.

My tier verdict: B+. B-grade spreadsheet, A-grade ceiling, and a nerf aimed at exactly the button bad players waste.

The full kit: what every button does

All mechanics from the MLBB Fandom hero page, checked 21 October 2026. Base HP 2320→4420, mana 500→1900, Physical Attack 110→222, Physical Defense 22→82, Magic Defense 15→45, Attack Speed 1.03→1.17, Movement Speed 250, basic attack range 4.5. Moonton's ratings (via tracker mirrors): Offense 9, Durability 4, Control 2, Difficulty 7 — a cannon that folds if sat on.

Passive — Heavenly Vow: he attacks with his longbow at range and his glaive in melee, chosen automatically by his distance to the target. Weapon Mastery: after each weapon swap, his next two basic attacks gain extra Attack Speed and deal 70% and 55% Crit Damage respectively, plus 15% Movement Speed for 1s. Everything in this kit exists to manufacture swaps. (Mirrors still print a fleet-arrival line — a fleet reaches base every 180s or on respawn; Fandom trivia: the only hero who changes how the allied base looks. Flavour, not a mechanic.)
Skill 1 — Traceless: dash forward and slash with the glaive for 150–300 (+40% Total Physical Attack), immune to control effects for 1s. Every Weapon Mastery triggered cuts its cooldown by 1s. Mana 50–75. Cooldown is the 2.2.16 story: the hero page still prints 12.0→7.0s, but the patch raised the top end — read it as 12→9s.
Skill 2 — Blood Floods: flat 11.0s cooldown, mana 60–85. Tap: an instant glaive slash, 240–340 (+80% Total Physical Attack). Hold: a charged arrow for the same base damage, scaling with hold time up to 200%. Either way, Weapon Mastery triggers immediately — your swap-on-demand button. Fine print: about 0.25s of holding separates tap from hold, and a landed arrow plays an impact sound even on enemies you can't see. Free information, if you're listening.
Ultimate — Mountain Shocker: flat 60.0s cooldown (starting on the *first* cast), mana 150–210. First press: he summons the turtle ship and gains sight of the whole map for 5s; the ship lasts up to 15s and he gains a 70% Movement Speed burst decaying to 20% over 2s. Recast: the ship rams a target area (range 5.7) for 160–320 (+65% Total Physical Attack) with a 0.8s stun in the central area, then the fleet fires three cannon waves over 2s, each 160–320 (+65% Total Physical Attack) with a 30% slow. Table-versus-prose flag: Fandom's level table prints 150/225/300 where the prose prints 160–320 — I quote the prose. Fine print: the reveal ignores untargetable enemies but pierces even Yin's domain; revealed enemies you never touch still credit an assist; and despite the skill text, Fandom's notes say Weapon Mastery pays on the recast, not the first cast.

Skill priority, my way: Ultimate whenever it opens > Blood Floods (your damage and your free swap, and with a flat cooldown every level is pure damage) > Traceless (post-nerf its levels buy less cooldown — one more reason the nerf bites).

Combos

The bread-and-butter pick: open at bow range and spend the mastery pair, Blood Floods for a fresh pair (tap in melee, short hold at range), then Traceless *through* the target to flip into glaive and cash the melee pair. Every step is a swap; every swap is damage.
The objective opener: Mountain Shocker's first cast for the reveal, ride the Movement Speed burst to the flank angle, and recast the ram onto the choke the moment your front line makes contact — stun centre, cannons behind it, mastery pairs while they scatter.
The fog snipe: hold Blood Floods from a bush or over terrain toward the full 200%, cash the mastery pair, and hold Traceless until their dash is spent — chase with it, don't greet with it.
The camp clear: start every camp at bow range, step across the line for the glaive pair, then Blood Floods or Traceless to force the next swap before you leave. Standing on one side of the line auto-attacking is playing half a hero at half speed.

Rotation and map control

Jungle is home — Retribution is non-negotiable and the Assassin emblem's Seasoned Hunter talent is built for him. The first phase is a schedule, not an adventure: clear by deliberately crossing the range line on every camp, hit level 4 on time, and arrive at the first Turtle with Mountain Shocker *held*. That Turtle is a timing check, not a duel invitation — he finishes river fights fast but hates being the first body seen in the choke. Invade only when your mid and roam have already moved first; a low-percentage invade that delays his item curve hurts him more than sturdier junglers, because his takeover window is item-driven.

The reveal is a rotation tool, not a panic button. Cast it before the last river bush and let the information choose your side of the fight; cast it after a failed engage and you're documenting the loss. And because the ult is global, the classic trap is farming the far lane like a split-pusher: he isn't one. His pressure is arriving at the right fight with perfect information, one rotation away — not clearing a vanity wave twenty seconds from the Lord pit. MLBBDex's note hangs over all of it: his win rate decays to average after minute twelve, so the tempo game has a deadline. Snowball the spike and close on schedule.

Best build, emblem, and battle spell (Season 42)

Boots — Tough Boots by default: MLBBHub, MLBBGuides' default build and ONE Esports' build all land there. Traceless covers one slice of control; the boots cover the rest. Warrior Boots only when enemy damage is overwhelmingly physical and their CC is light.
Core — War Axe, then Endless Battle, then Blade of Despair. MLBBHub and MLBBGuides agree on the spine (Guides' default: Tough Boots, War Axe, Endless Battle, Blade of Despair, Malefic Roar, Immortality). The real spike is the first two — War Axe plus Endless Battle, roughly 7:30–9:30 in a clean game: health and cooldown so the melee step stops being a suicide note, and Divine Justice true damage on every skill-to-basic weave. Before it, scout and soften. After it, hunt.
Flex slots: Malefic Roar when the front line turns the game into an armour check. Blade of the Heptaseas when snowballing into fog picks. Hunter Strike when targets keep slipping first contact and fights become chases. Rose Gold Meteor against burst. Immortality last, when one death decides the game.
Emblem — Assassin: Rupture, Seasoned Hunter, Killing Spree (MLBBHub's setup; older build archives list the same three). Penetration for the pairs, jungle damage for the tempo, a kill-reset for a hero who chains swaps across a fight.
Battle spell — Retribution. Jungle footwear is locked behind it. Ice Retribution is ONE Esports' flavour, for the smite-duel slow.

How to counter him

Out-duel him in his own range. Lancelot is the headline answer — MLCounter has Yi Sun-shin winning just 43% of that matchup, and MLBBHub names him a trap-game pick alongside Akai (displacement) and Helcurt (hidden dive): all three tax his need for a reset window once he commits to glaive range. Karina sits on both MLBBHub's measured list and MLCounter's table (he wins 49% against her), and MLCounter's worst matchup of all is Alucard, at 42%.
Suppress him. MLBBGuides flags Franco and Kaja as his difficult opponents: Traceless grants control immunity, not suppression immunity — one Bloody Hunt or Divine Judgment stops the swap engine mid-sentence.
The Uranus argument. MLBBHub's measured data names Uranus among his biggest counters; MLBBGuides lists Uranus as a *favourable* target. Both are printed because both are real data — my read: regen tanks outlast his burst cycles in even games, while a fed admiral kills everything standing next to the tank instead.
Play the windows. Post-nerf Traceless is his longest leash — force it out defensively early and he's a marksman with a knife for several seconds. The ult is 60 flat seconds; bait the reveal, wait out the ship, then fight. Never stack three bodies in a choke while the ship is up — the centre stun plus three cannon waves is priced for that mistake. Winter Crown and Tough Boots are the item answers.
Who he eats: MLCounter has him beating Fanny 58% — the global reveal is a rude surprise for a hero who lives on unseen engages — plus Sun 54%, Chou 53% and Nana 52%. MLBBGuides' favourable list adds Terizla, Harley, Lesley, Kimmy and Ling. Immobile backlines and stealth divers hate a jungler who lights up the whole map every 60 seconds.

Mistakes everyone makes

"The Greeting Dash": Traceless as the opener into Akai, Helcurt or Lancelot. It is the button that *saves* the duel, not the one that starts it — and after the 2.2.16 cooldown raise, the dash burned saying hello was the one meant to get you home. MLBBHub calls it his most expensive mistake; the patch made it pricier.
"The Postcard Ultimate": casting Mountain Shocker from base, or after your front line is already dead. The reveal's value is choosing the entry *before* the fight; a late ult is a dramatic screenshot of a loss.
"The Statue Arrow": holding Blood Floods to full charge in open vision. Every beat spent charging in front of the enemy is a beat their assassin spends aiming at a stationary target. Charge from fog or before contact; in a live fight, the instant tap pays the mastery pair sooner.
"The Far-Lane Tourist": split-pushing the far lane because "the ultimate is global anyway." The ult is global; *you* are not. Be one rotation from the objective, not twenty seconds.
"The One-Range Farmer": parking at one distance on camps and objectives, never forcing a swap. No swaps, no mastery pairs, no Traceless refunds — the slowest clear in the jungle wearing an assassin's badge.

FAQ

Is he still worth learning after the 2.2.16 nerf? Yes. The nerf taxes dash frequency, not damage — loop, reveal and ram are untouched. You can't afford to waste the bridge anymore.
Bow or glaive — which does more damage? Neither. The *swap* does. The mastery pair after a weapon change is the burst; park in one range and you're playing half a passive.
When do I actually press Mountain Shocker? Before objectives and dark-river walks — early enough that the ship matters when the fight starts, close enough that the ram threatens, not decorates.
Why does he feel weaker late game? Because he is, relatively: MLBBDex notes his win rate returns to average after minute twelve. He's a tempo jungler with a mid-game spike, not late-game insurance.
Is the bleed build real? No. The current kit has no bleed at all — that's the retired version of the hero still haunting old guides. Don't build for a ghost.

Final verdict

Yi Sun-shin is the jungler for players who think in information and tempo. Nobody else in the role gets to check the whole map's homework every 60 seconds. The 2.2.16 nerf was Moonton admitting his dash uptime had become rude — and even nerfed, the most-played jungler in Mythical Glory (per MLBBDex) isn't going anywhere. But the B+ is honest — average hands produce a 49.8% hero, because the gap between swapping on purpose and pressing buttons in some order is the whole champion. Learn the loop and he's an admiral. Skip it and he's a man at a sword fight holding a bow.

Play him if: you enjoy jungling as a decision-making contest, you'll practise crossing the range line on purpose, and your team has someone else to touch the fight first.

Skip him if: you want a dash you can spend carelessly, you hate early-game schedules, or your idea of an ultimate is a button you press when things are already going wrong.
