Let's dive into the chaotic depths of Mobile Legends Bang Bang's latest update. With Mobile Legends Bang Bang Patch 1.9.99, with the new Project NEXT's massive overhaul, there are thrilling new things to enjoy. Among them, the Mobile Legends Bang Bang Obsidia stands out as the fresh marksman-assassin hybrid ready to shred enemy backlines. If you're searching for the best Obsidia build Patch 1.9.99, Obsidia guide Project NEXT, or how to play Obsidia MLBB effectively, this guide is here to cover them all for you.
Obsidia Hero Overview: Who Is She and Why Pick Her in Patch 1.9.99?
The arrival of Obsidia, the Goddess of Death, on September 17, 2025, marked a fresh twist in Project NEXT's hero lineup. So, what is the role of Obsidia MLBB? She is designed as a marksman with assassin undertones, and Obsidia thrives in the Gold Lane, scaling into a hyper-carry that punishes isolated enemies with rapid on-hit effects and her signature Bone Energy tether.
Her gameplay favors constant pokes early on, later snowballing into a nightmare for teams caught in tight skirmishes. What makes her stand out in Patch 1.9.99 is her ultimate's anti-mobility mechanic, which shuts down blink-heavy opponents, a huge asset on the reworked map where fights break out faster and chokepoints force close combat.
She's a perfect fit for teams that need a strong backline threat without overextending. Current stats back this up, with her win rate hovering around 52% in the Gold Lane. Still, she's fragile in the early stages and struggles outside the lane since jungle monsters don't trigger her Bone Energy, leaving her exposed if over-rotated.
Key Traits:
Strengths: Exceptional attack speed scaling, anti-mobility ultimate, devastating single-target burst.
Weaknesses: Fragile before items, no jungle potential, prone to kiting.
Best Obsidia Build for Mobile Legends Patch 1.9.99: Attack Effect Focus
Obsidia's passive relies on chaining basic attacks and triggering on-hit effects, so her build prioritizes attack speed, penetration, and survivability over crit. With Project NEXT accelerating combat pacing, this setup helps her pile up Bone Shards quickly while surviving dives and ganks. So you can swap in anti-heal or burst gear depending on the matchup.
Recommended Build Path
Swift Boots – +40 Movement Speed, +15% Attack Speed. Core for dodging early poke and speeding through Gold Lane farming.
Corrosion Scythe – +70 Physical Attack, +5% Movement Speed. Provides stacking damage and a 40% slow for easier kiting.
Demon Hunter Sword – +35 Physical Attack. Deals bonus percentage damage to low-HP targets, making her lethal against tanks and bruisers.
Golden Staff – +65% Attack Speed. Converts 40% of Physical Attack into true damage, enhancing Bone Shard detonations.
Malefic Gun – +70 Physical Attack, +25% Attack Speed. Grants armor penetration after every five hits, breaking through frontlines.
Rose Gold Meteor – Defensive safety net with +60 Physical Defense, +30 Magic Resistance, and a 1,200 HP shield when health drops.

Optimal Emblem Setup: Marksman for Speed and Shred
Mobile Legends Obsidiaperforms best with the Marksman Emblem since it maximizes her shard-stacking and late-game carry potential. Assassin can work for early snowballs, but it lacks the same scaling power that makes her dangerous in extended fights.
Recommended Talents
Tier 1: Swift – +6% Attack Speed to stack Bone Shards from the very first wave.
Tier 2: Weapons Master – +12 Physical Attack, plus +6% bonus damage, boosting shard procs and every on-hit effect.
Tier 3: Weakness Finder – 30% Attack Speed slow and 50% Movement Speed slow for 1.5 seconds on hit, making chase downs almost guaranteed.
This combination also provides +21% hybrid penetration at early levels, letting her pressure Gold Lane opponents before her core items are online.
Best Battle Spells: Mobility First
Obsidia is fragile and immobile on her own, so the right spell often decides whether she carries or collapses.
Flicker (Primary) – Essential for repositioning during teamfights or escaping dives. Works perfectly with the new Project NEXT map's extra walls.
Sprint (Secondary Option) – 85% Movement Speed boost for 2 seconds, great for rotations or dodging assassins.
Purify (Situational) – Counters heavy CC lineups, especially against heroes like Selena or Aurora.
Skill Upgrade Path: Prioritize Poke, Then Lockdown
Obsidia's kit rewards consistent pokes to generate energy, so leveling choices should maximize her shard uptime while keeping her ultimate available as often as possible.
Start with Skill 1 (Abyssal Bone Needle) at level 1 for poke and shard farming.
Max Order: Skill 1 > Ultimate > Skill 2.
Full Leveling Sequence: S1 → S2 → Ult → S1 → Ult → S1 → S2 → S1 → Ult → S2 → Ult → S1 → S2 → S2 → Ult → S2.
This path ensures constant lane pressure and enables ults roughly every 30 seconds by mid-game, letting her dictate fights without overcommitting. And for anyone who focuses more on collecting Obsidia, the best diamond packs are exclusively available at LootBar with an Obsidia Event Pass. Before the time runs out, it is better to top up Mobile Legends Bang Bang with this opportunity.
Obsidia Skills Breakdown: Mastering the Bone Arsenal
Obsidia thrives on stacking and spending Bone Energy, so understanding her kit is key to controlling Gold Lane and dominating skirmishes.
Passive – Return to Bone: Every hit, whether basic attacks on heroes or minions, or skill damage, generates Bone Energy. At 100 energy, a Bone Shard forms (max five stacks). Using Basics consumes all shards, dealing 120% total Physical Attack + 8% of the target's max HP as bonus damage per shard. Hero kills refresh two shards, giving her near-endless sustain in prolonged fights.
Skill 1 – Abyssal Bone Needle (Cooldown: 7–4s, Mana: 50): Pierces the first enemy hit for 200–400 (+100% Physical Attack) Physical Damage and triggers passive energy gain. Great for poking, wave control, and preparing Bone Shards. Spam S1 early to dominate lanes without overextending.
Skill 2 – Phantom Shadowmeld (Cooldown: 12–8s, Mana: 60): Dive into shadows for 2s, gaining +60% Movement Speed (up to 1.5s in Ult). Use as a dodge, flank tool, or gap-closer. It's her mobility button, letting you weave through minion waves or reposition for ultimate setups.
Ultimate – Hunt of Bone (Cooldown: 40–30s, Mana: 100): Unleash Bone projectiles that deal 300–500 (+120% Physical Attack) damage, stunning for 0.5s and tethering the first hero hit for 3s. While tethered, dashes/blinks are disabled, three instant shards are granted, S2 is empowered for 4s (2s cooldown), and you can wall-phase to reposition. Perfect for dragging isolated enemies into your team for easy picks.
Deadly Combos: From Poke to Delete
Obsidia's power spikes when you chain Bone Energy into her ultimate. So, practice these combos for Mythic-level plays:
Basic Poke Combo (Early Lane Harassment): S1 → Auto → S1 → Auto. Generates 2–3 shards per wave, whittling HP safely without overcommitting.
Engage Shred (Mid-Game Gank): S2 (approach) → S1 (poke) → Ult (tether) → Auto spam (Bone Shards detonate during drag). Follow with S2-empowered attacks for cleanup, dealing 1,500+ damage.
Teamfight Finisher (Late Game Ult Dive): Wait for an engage → S1 on backline → Flicker + Ult → S2 loops → Autos. Isolate the enemy carry while your tank absorbs frontline pressure.
Pro Tip: Use Ult through walls for unexpected angles on the new Project NEXT terrain, catching opponents off-guard.
Playstyle Guide: From Farm to Fame in MLBB Project NEXT
Early Game (Levels 1–7, Gold Lane Focus)
Prioritize safe farming under the tower while poking with S1 to control lane pressure. Last-hit minions efficiently and use S1 to harass roaming opponents. Rotate to mid around the 4-minute mark for objectives like Turtle. Key goal: reach level 4 ultimate before the 5-minute mark. Pair with tanks like Tigreal to provide peel and protection for safer farming.
Mid Game (Levels 8–12, Skirmish King)
Focus on 2v2 or 3v3 skirmishes around objectives. Use S2 to dodge skillshots and reposition, especially against mobile threats like Ling. Shard management is crucial—prioritize generating Bone Shards over risky all-ins. Aim for around 50 CS per minute while participating in fights that yield objectives or kills.
Late Game (Levels 13+, Hyper-Carry Mode)
Transition to backline siege. Keep at least 40% HP to survive poke, then use ultimate to peel divers or delete enemy mages. During Lord fights, tether enemy junglers to zone them out and create pick opportunities. Win condition: 5 Bone Shards + ultimate = near-instantly delete squishy targets.
Obsidia Counters and Matchups: Who to Ban, Who to Bully
Hard Counters (Ban These)
Burst Assassins: Saber, Gusion—can dive and eliminate you before you stack Bone Shards.
CC Lockdown: Chou, Guinevere—stun chains can interrupt your ultimate tether.
Kite Marksmen: Granger, Lesley—out-range your poke during early lane phases.
Favorable Matchups
Blink Reliant Heroes: Joy, Lancelot—your ultimate neutralizes their mobility, making engages easy.
Tanks: Easily shredable with Demon Hunter Sword procs.
Immobile Gold Laners: Bully heroes like Clint; avoid highly mobile laners like Bruno.
Item Counters
Wind of Nature helps against heavy physical CC, while Dominance Ice slows enemies, mitigating their movement and attack speed against you. The best way to bring these to the gameplay is LootBar, as it has the best packs to buy at an average amount of price without spending too much.
Conclusion
And that is it. This is the definitive Mobile Legends Obsidiaguide for Project NEXT, optimized for aggressive Gold Lane dominance and late-game teamfight wipes. Stick to attack-effect builds for consistent damage output, manage Bone Shards efficiently, and use her anti-dash ultimate to control the patch's mobility-heavy meta as we recommended here.
