Quick Answer: Patch 1.9.20 nerfs Edith, Zhuxin, and Kagura while buffing Lukas, Suyou, Saber, and Aurora. New Support hero Marcel (599 Diamonds) drops March 11, 2026 alongside Season 40. Top Diamond picks: Gloo (Tank), Sora (Fighter), Helcurt (Assassin), Marcel (Support). Avoid Edith and Kagura until win rates stabilize.
What Patch 1.9.20 Actually Changed
This isn't a cosmetic update — it directly reshapes which heroes dominate Epic through Mythic in March 2026. Read patch notes before opening your wallet. A hero that was S-tier last patch may be B-tier today.
Key Nerfs
Edith: Total Magic Power Bonus cut from 30% → 20%; Bonus Damage formula dropped from 4% + 0.25% × Hero Level to 3% + 0.2% × Hero Level
Zhuxin: Base Mana reduced 1500 → 1200; Skill 2 Soul Snare mana cost changed from flat 100–150 to 90–150 (hurts early-game sustain)
Kagura: Ultimate magic power scaling 105% → 90%; base damage ratio 70% → 60%; Skill damage 170% → 155%
Key Buffs
Lukas: Skill 1 max stacks now trigger Stun instead of Airborne; Skill 2 Extra Damage up from 5–30 + 20% Total Physical Attack to 40 + 25%; Flash Strike Damage up from 20–120 + 120% to 60–120 + 125% Total Physical Attack
Suyou: Skill 1 Hold-cast control upgraded from 0.5s Airborne to 0.6s Stun — Stun can't be cleansed by certain items, a genuine quality upgrade
Saber: Base HP 2400 → 2500; Physical Defense 180 → 200; Defense growth 4.1 → 4.5 per level; Skill 1 cooldown halved from 1s → 0.5s
Aurora: Skill 1 cooldown scaling improved from 6s–4s to 6s–3s; Skill 2 from 12s–9s to 12s–8s
Eudora: Skill 1 mana cost reduced from 65/90 to 60/85
Why This Matters
Edith's hybrid tank-mage identity depended on that magic power conversion bonus — a 10-point reduction meaningfully lowers her teamfight damage ceiling. Zhuxin's mana cut limits mid-game roaming windows in coordinated Mythic play. Lukas's Stun upgrade is a genuine CC improvement; Stun is harder to counter than Airborne at high level, and his raw Flash Strike numbers are substantially higher. Saber's buffs are rework-level — he's a legitimate threat again.
How to Evaluate Any Hero Before Spending Diamonds
Apply this three-metric filter before committing to any purchase.
Win Rate: Target heroes above 52% in your rank bracket within the first week post-patch. Early data is noisy but directionally reliable.
Pick Rate: High pick + high win = genuine meta dominance. High pick + low win = overhyped.
Ban Rate: 40%+ ban rate in Mythic confirms real impact — but expect inconsistent access.
Red Flags: Skip These Heroes Right Now
Received damage or scaling nerfs this patch
Primary mechanic countered by a new item or system change
Win rate was already declining pre-patch
A direct role competitor got buffed in the same update
March 2026 ranked queues trend toward durable frontlines and reliable CC chains. Pure burst mages without mobility (post-nerf Kagura) are losing priority to versatile options.
Best Heroes to Buy with Diamonds — Patch 1.9.20 Tier Breakdown
S-Tier: Buy Now
Gloo (Tank) — Split-body mechanics untouched by this patch; current win/ban rate data is clean and reliable
Sora (Fighter) — Sustained damage and mobility thrive in the skirmish-heavy meta
Helcurt (Assassin) — Solo-carry potential; silence mechanic becomes more valuable as CC-dependent heroes rise
Yi Sun-Shin (Assassin) — Global ultimate provides map pressure that fits the objective-focused ranked environment
A-Tier: Strong Value
Lukas — Direct buffs this patch; Stun upgrade and improved Flash Strike make him the highest-value Fighter/Assassin purchase right now
Saber — 100 extra base HP, 20 more Physical Defense, improved defense growth, halved Skill 1 cooldown push him back to A-tier
Aurora — Faster cooldown scaling on both skills increases burst rotation frequency significantly
Avoid Spending Diamonds On
Edith — Magic power and damage formula nerfs reduce teamfight value; wait for win-rate stabilization
Kagura — Triple nerf across Ultimate scaling, base damage ratio, and Skill damage; poor investment at current pricing
Zhuxin — Mana reduction weakens roaming effectiveness and late-game value
Mage and Assassin Deep Dive
Aurora: Best Mage Pick Post-Patch
Skill 1 now scales to 3s cooldown at max level (down from 4s). Skill 2 minimum cooldown drops to 8s (from 9s). In a meta where durable frontlines are rising, a Mage who reliably freeze-chains priority targets every few seconds is exponentially more valuable. She pairs exceptionally with Gloo — his split mechanics force enemies into predictable positions, creating clean freeze targets.
Eudora's mana cost reduction (Skill 1: 65/90 → 60/85) extends lane presence and burst combo frequency. Minor buff, but meaningful for sustained mid-game skirmishes.
Helcurt and Yi Sun-Shin: Top Assassin Picks
Helcurt's silence directly counters CC-heavy compositions rising in this meta. Silencing a Suyou or Aurora before they execute control chains is decisive in Mythic lobbies. Yi Sun-Shin's global ultimate complements the current objective-focused environment.
Pro tip: Helcurt's silence is most impactful in the 3–8 minute window when enemies have committed to CC-dependent rotations but haven't built Purify or cleanse items yet.
Tank, Fighter, and Support Picks
Gloo: Top Tank Investment
Most disruptive Tank in March 2026. Split-body mechanics create positioning chaos that most teams struggle to counter without dedicated preparation. Patch 1.9.20 doesn't touch him — his data is reliable for investment decisions.
Sora and Lukas: Best Fighters
Sora holds S-tier with sustained damage and mobility suited to skirmish-heavy play. Lukas's Stun on Skill 1 max stacks enables follow-up CC chains that Airborne didn't reliably allow — when he lands max-stack Skill 1, your team has a clean 1-second window to layer additional CC. That's the kind of synergy win-rate data captures but doesn't explain.
In practice: Don't use Lukas's Flash Strike as an opener. It deals maximum value as a finisher after Skill 1 stacks are built.
Marcel: The Support Hero Worth Your Diamonds
Marcel is the 132nd hero, releasing March 11, 2026 at 599 Diamonds or 32,000 Battle Points. His kit:
Platinum Snap (Passive): Deals true damage equal to 40% Total Physical Attack + 40% Physical Defense + 40% Magic Defense, then shields Marcel for the same combined amount. Per-target cooldown: 8 seconds
Framed Moment (Skill): Charges in 2.5 seconds; immobilizes targets for 1 second; deals 400–700 base damage + 50% Total Physical Attack, scaling with 100% Physical Defense + 100% Magic Defense
Golden Hour (Ultimate): Creates a 3-second Frozen Moment that reduces incoming projectile damage by 50%, freezes minions and jungle objectives, and fully resets Platinum Snap's cooldown
His Frozen Moment ultimate has a counterintuitive strength: freezing jungle objectives during a contest forces enemies to either wait or engage without ranged poke — heavily favoring teams with superior melee fighters. Season 40 launches March 3–11, 2026, so early adopters gain a ranked advantage before the broader player base learns his counters.
Don't play Marcel as a damage dealer. Platinum Snap's true damage is a bonus, not his primary identity.
Diamond Cost vs. Meta Value
Pricing Overview
Marcel: 599 Diamonds or 32,000 BP
Gloo, Sora, Helcurt, Yi Sun-Shin: Standard hero pricing tiers; check in-game Hero Shop for current costs and limited-time discounts
Lukas, Saber, Aurora, Eudora: Mid-range Diamond costs with strong post-patch value
Buy Now vs. Wait for Discount
For S-tier heroes with high ban rates (Gloo, Helcurt), buy immediately — every session you delay is a session without your optimal pick. For A-tier heroes like Saber or Aurora, waiting for a discount event or using accumulated BP is reasonable since their dominance is strong but not ban-worthy.
To buy mobile legends diamonds cheap before Marcel's March 11 release, BitTopup offers fast, secure Diamond delivery — so you don't miss the launch-window advantage due to top-up delays.
Free-to-Play Substitutes
Aurora and Eudora are both accessible through BP grinding. If your Diamond budget is tight, prioritize Marcel (Support) and Gloo (Tank) as Diamond purchases, then work toward Aurora and Eudora through BP. Saber's buff makes him a strong BP target too — his Diamond cost may not justify the spend when BP is available.
To top up MLBB diamonds instantly, BitTopup ensures you're topped up before any launch window closes.
FAQ
Which heroes are best to buy with Diamonds in Patch 1.9.20? Gloo (Tank), Sora (Fighter), Helcurt (Assassin), Marcel (Support, March 11), and Lukas (Fighter/Assassin). These heroes either received direct buffs or remain untouched while their counters were nerfed.
Can a nerfed hero still be worth buying? Rarely in the short term. Edith and Kagura took meaningful damage nerfs — wait at least two weeks post-patch for win rates to stabilize before committing Diamonds, unless you play them in non-damage-dependent roles.
How much does Marcel cost in March 2026? 599 Diamonds or 32,000 Battle Points. He releases March 11, 2026 as the 132nd hero, classified as Support.
Are Diamonds better than Battle Points for hero purchases? Diamonds unlock heroes immediately and are the only option during a new hero's launch window. BP is better for older heroes when you have time to grind. For meta-critical heroes like Marcel at launch, Diamonds provide a competitive timing advantage BP can't match.
How often does MLBB release meta-shifting balance patches? Major patches arrive every two to four weeks. Season transitions (Season 40 launches March 3–11, 2026) often coincide with larger meta shifts. Check patch notes at every update cycle before any Diamond purchase.
What's the best Support hero to buy after Patch 1.9.20? Marcel. His Platinum Snap true damage scaling, Framed Moment immobilization, and Golden Hour ultimate — which resets cooldowns and cuts incoming projectile damage by 50% — give him a uniquely disruptive kit no current Support replicates. At 599 Diamonds, the launch-window ranked advantage justifies the investment.
