Guide to Obsidia — New Hero in Mobile Legends: Bang Bang

Obsidia, the Mistress of the Dark Realm, joined Mobile Legends: Bang Bang on September 17 as part of the massive Project NEXT 2025 update. She becomes the 130th hero in the game and the first classic marksman in a long time with a unique Bone Shard accumulation mechanic, making her a true late-game monster with incredible single-target power.

Obsidia represents the perfect blend of a traditional marksman with assassin elements, capable of blocking enemy mobility and providing the team with critical eliminations.

Lore and Backstory of Obsidia

In the depths of the vast dark Abyss, Obsidia once reigned as the undisputed mistress, wielding power few could comprehend. However, her downfall began when the Dark God spread his malignant influence throughout the Abyss, turning its inhabitants into puppets without their own will.

Obsidia fell victim to this corruption, losing her free will and becoming a mere tool of divine power—a fate worse than death. Alice and Thamuz, seeking their own power and status, betrayed their former mistress, leaving her in exile.

For centuries, she remained in a dormant state until she awoke again, determined to reclaim her spiritual sovereignty.

Her awakening symbolizes not just a return to power but a fight for true freedom—a state where no entity, mortal or divine, can subjugate her will. Now she seeks revenge on those who betrayed her and to restore her status as the sole true mistress of the Abyss.

Key Abilities of Obsidia

Passive – Return to Bone 

• The heart of Obsidia's power lies in her passive ability to accumulate Bone Shards. When Obsidia deals damage to enemy heroes, minions, or structures, she gains Bone Energy, which converts into Bone Shards with a maximum limit of 25 pieces.
•  With each basic attack, all accumulated shards automatically fly to the target, dealing additional physical damage and partially inheriting item effects.
• Killing an enemy hero instantly grants an additional shard, encouraging aggressive play. This mechanic makes her basic attacks resemble a machine gun when she has accumulated multiple shards.

Skill 1 – Abyssal Bone Needle

• Obsidia releases a bone needle straight forward, dealing damage to the first target. 
• Hitting an enemy hero activates the passive ability, granting additional Bone Energy. 
• With a short cooldown, this ability serves as both a harass tool and a quick way to gather shards.

Skill 2 – Phantom Shadowmeld

• Obsidia dives into the Abyss, gaining significant movement speed for a short time. 
• This ability becomes much more powerful during the ultimate's effect—increasing duration and reducing cooldown, giving her almost constant mobility.

Ultimate – Hunt of Bone

• The ultimate is Obsidia's most defining ability. She releases the Bones of Wrath in a chosen direction, which attach to the first enemy hero, stunning them and pulling Obsidia towards the target.

priority targets. This makes her an ideal counter against mobile heroes like Fanny, Ling, or Hayabusa.

Skill Leveling Priority for Obsidia

Maximizing Obsidia's efficiency is achieved by correctly distributing skill points throughout the game. Prioritize maxing out the Q skill to ensure consistent damage and quick passive accumulation.

Runes and Emblems for Obsidia

Obsidia works best with the Marksman emblem, utilizing the Swift talent for additional attack speed, Weapon Master for increased damage, and Weakness Finder for slowing enemies. Alternatively, Penetration can be used against tank-heavy team compositions.

These runes allow Obsidia to quickly accumulate passive stacks due to increased attack speed, which is critical for lane dominance and effective scaling in team fights.

Build for Obsidia

• Standard build: Windtalker → Berserker's Fury → Demon Hunter Sword → Haas' Claws → Malefic Roar

Situational Options

• Trinity build: For teams with high durability, use an attack speed build to help gather passive faster.
