Obsidia

CTier

Marksman who stacks basic-attack shards into a stun-and-tether execute

MarksmanGold LaneDeals physical

Obsidia is a gold-lane marksman who builds Bone Energy from every hit — basic attacks and skills alike — until it forms Bone Shards that unload on her next auto-attack. Phantom Shadowmeld's burst of speed repositions her mid-fight, and Hunt of Bone tethers a target in place with a stun, turning a chase into a guaranteed finish.

Difficulty: Moderate
Specialities: FinisherDamage

Timing Return to Bone's shard stacking against Hunt of Bone's short tether range takes practice, but the core basic-attack loop is straightforward compared to combo-heavy marksmen.

Strengths

Return to Bone stacks Bone Shards off both basic attacks and skills, giving her burst that scales faster than a normal marksman's auto-attacks alone
Phantom Shadowmeld's burst of speed repositions her instantly, dodging a skillshot or closing a gap in a single beat
Hunt of Bone stuns, tethers, and pulls a fleeing target, turning what would be a missed kill into a guaranteed one
Abyssal Bone Needle hits in an AoE line, letting her stack Bone Energy against grouped enemies rather than just a single target

Weaknesses

Very low HP and no defensive skill outside Phantom Shadowmeld's brief 0.3-second speed burst
Hunt of Bone's tether only reaches 4 units, so a target with a hard displacement skill can still break free
Bone Shard stacking loses value if she's forced off the fight before unloading them on a basic attack
No ranged poke tool beyond Abyssal Bone Needle's short-cooldown skill, leaving her reliant on auto-attack range to farm shards

Skills

Max Abyssal Bone Needle first to stack Bone Energy and Return to Bone's shards fastest, level Phantom Shadowmeld whenever available for the mobility, and take Hunt of Bone at levels 4, 8 and 12.

Passive

Return to Bone

Buff

When Obsidia deals damage to enemies, she gains Bone Energy (Basic Attacks against non-hero units grant 1 Energy, against hero units grant 2 Energy, and skills grant 3 times the Energy. No Energy is gained from hitting creeps). When Bone Energy reaches 30, it forms a Bone Shard, up to 25 shards. When Obsidia uses Basic Attacks, all Bone Shards strike the target, each dealing (7% Total Physical Attack) Physical Damage and inheriting 7% Attack Effects.

Always active — no cooldown

Skill 1

Abyssal Bone Needle

DamageAOE

Obsidia launches an Abyssal Bone Needle dealing 325 (+80% Total Physical Attack) Physical Damage to enemies hit and triggering Return to Bone on the first enemy hero attack.

Cooldown: 4.5s
Mana: 35 → 50

Skill 2

Phantom Shadowmeld

Speed Up

Obsidia descends into the Abyss and enters Shadowmeld Form, gaining 500% Movement Speed for 0.3s.

Cooldown: 4.5s
Mana: 35 → 60

Ultimate

Hunt of Bone

CCMobility

Obsidia shoots Bones of Wrath, in the target direction, dealing 125 (+60% Total Physical Attack) Physical Damage and briefly stunning the first enemy hero hit, and pulls herself near them. The Bones of Wrath then tether to the enemy, preventing Obsidia from moving more than 4 units away from them. The enemy cannot use displacement skills, and their movement will pull Obsidia along. During this time, Obsidia gains 5 temporary Bone Shard(s). This effect lasts 3s.

Purify90s CD

Purify does not clear suppression (e.g. Franco's Bloody Hunt or Khufra's ultimate) — a common mistake is trusting it to escape a hook combo it can't actually cleanse.

Playing Obsidia well

1
Open trades with Abyssal Bone Needle to trigger Return to Bone before you're even in auto-attack range
2
Save Hunt of Bone for a target already below the HP threshold where the tether's stun and pull guarantee the kill, not as an opener
3
Use Phantom Shadowmeld's speed burst to dodge a telegraphed skillshot mid-fight, not just to chase
4
Unload accumulated Bone Shards on a clean basic attack against an isolated target rather than the first enemy you see, since the shards proc all at once

Obsidia — common questions

Is Obsidia good for beginners?

She's approachable — the core loop of auto-attacking to stack Bone Shards is intuitive — but landing Hunt of Bone's short-range tether on a moving target takes real timing.

What is the best build for Obsidia?

Swift Boots into Windtalker, Berserker's Fury, and Malefic Roar covers the standard attack-speed scaling path. Swap to Demon Hunter Sword and Blade of Despair against a stacked-defense frontline.

Which heroes counter Obsidia?

Baxia Mark's flat per-hit reduction erases exactly the multi-hit pattern of her Bone Shards, Uranus regenerates off every hit she lands, and Odette can delete her before Hunt of Bone's short tether even matters.
