Mobile Legends Obsidia Guide: Best build, skills, emblems & combos

Obsidia is one of the most explosive late-game marksmen in Mobile Legends, built around snowballing her passive and turning every basic attack into a threat once she starts stacking up. Unlike traditional marksmen or scaling mages like Cecilion, she can’t farm stacks from jungle monsters, so putting her in the Jungle role completely cripples her kit. Instead, she shines in the Gold Lane, where constant trading and last-hitting let her ramp up Return to Bone and unlock her devastating on-hit damage. Her passive adds extra strikes based on how many stacks she’s earned, making her especially strong when combined with effect-triggering items. On top of that, her Ultimate lets her latch onto a target and chase them relentlessly, forcing enemies to either blow mobility skills instantly or get shredded. It’s a playstyle that rewards smart positioning, patient scaling, and knowing exactly when to stick to a target. In this guide, you’ll find everything you need to master Obsidia—from her best builds and emblem setups to how her skills work, her strongest combos, and which heroes to watch out for.

Obsidia Skills Overview in Mobile Legends

Obsidia’s kit revolves around stacking her passive and turning every basic attack into a deadly on-hit burst. Her passive, Return to Bone, charges up whenever she damages enemies with attacks or abilities—though jungle creeps don’t give her anything—eventually forming Bone Shards that unload extra Physical Damage every time she fires a basic attack, making on-hit items incredibly strong on her. Her first skill, Abyssal Bone Needle, throws a piercing projectile that deals damage and instantly feeds her passive when it connects with the first enemy hero. Phantom Shadowmeld, her second skill, lets her slip into the shadows and gain a burst of speed, helping her reposition, chase, or dodge incoming threats. Her ultimate, Hunt of Bone, is what makes her so terrifying in duels: she fires a wave of bone energy that hits and stuns the first enemy hero it touches, then yanks herself straight to them and tethers onto the target. While attached, she follows their movement, ignores terrain, locks out their displacement abilities, and keeps attacking nonstop while gaining temporary Bone Shards and a heavily enhanced version of Shadowmeld. This entire kit lets Obsidia stick to priority targets like glue and shred them if she’s allowed to stack uninterrupted.

How To Play Obsidia In Mobile Legends

Best Obsidia Item Build in Mobile Legends

For Obsidia, you want a build that maximizes her on-hit burst and lets her stack quickly, so the ideal path starts with Magic Boots to speed up your early cooldowns and help you spam Skill 1 more often. From there, Corrosion Scythe is a perfect second item because the attack speed, on-hit slow, and ramping damage all sync with her passive. Once you enter mid-game, pick up Demon Hunter Sword for melting tanky opponents, or swap it for Sea Halberd if the enemy lineup relies heavily on healing or shields. Follow that with Golden Staff, which transforms her Bone Shard procs into a nonstop barrage thanks to the huge attack speed spike. For late-game, Malefic Gun gives her the bonus basic attack range and penetration needed to pressure backliners, while Rose Gold Meteor adds a lifesaving shield for clutch fights. If you need more sustain, replace one defensive slot with Haas’s Claws, and if you snowball hard, grab Blade of Despair to push her damage output through the roof. This build turns Obsidia into a relentless marksman who sticks to targets and shreds them before they can escape.

Best Emblem and Battle Spell for Obsidia

For Obsidia’s emblem setup, the Custom Marksman Emblem is the best fit because it amplifies her on-hit damage and lets her build stacks much faster. Put Swift in the first slot to boost her attack speed right from the start since her entire kit benefits from firing off basic attacks as often as possible. In the second slot, Weapons Master adds extra scaling to every bit of damage she deals—this includes her Bone Shard procs, making it a huge value pick. For the final talent, Weakness Finder is perfect because the on-hit slow and attack speed reduction help Obsidia stick to targets longer and win extended trades. When it comes to battle spells, she desperately needs some form of mobility, so Flicker or Sprint are your most reliable choices for escaping dives or repositioning during fights. If the enemy team has heavy CC, Purify is worth picking to keep her from getting locked down. Avoid Retribution entirely, as Obsidia isn’t made for the Jungle role and gains no stacks from creeps anyway. This setup ensures smooth early trades and lets her scale hard into late-game teamfights.

Best Combo Tips to Learn for Obsidia

To get the most out of Obsidia, always try to farm Bone Energy efficiently by hitting multiple enemies with Abyssal Bone Needle, especially enemy heroes, since they give the fastest stack generation. Her Ultimate is incredibly strong for locking down squishy targets, but avoid using it on heroes with damage reflection effects like Belerick or anyone running Vengeance—you’ll melt yourself faster than you can burst them. Obsidia works best when diving the enemy backline, picking off mages and marksmen who can’t escape her tether. Just remember that she has almost no real disengage aside from Phantom Shadowmeld, so never run in first during team fights. Let your tanks start the engagement, slip in from the side, and commit only when the enemy has burned their major CC. This playstyle keeps you alive longer and lets you ramp up your Bone Shard damage safely, which is where Obsidia truly shines.

Conclusion

Obsidia is one of those late-game monsters in Mobile Legends who becomes scarier the longer a match goes on, and learning how to manage her Bone Energy stacks is the key to unlocking her full potential. With the right build, emblem setup, and smart positioning, she can shred through teams using nonstop on-hit pressure and her deadly tether ultimate. While she’s fragile and lacks mobility, careful timing and good target selection turn her into a reliable backline destroyer who can carry fights once she’s fully stacked. Master her pacing, stay protected behind your frontline, and you’ll quickly see why Obsidia is becoming a favorite for players who love relentless DPS heroes.
