Overview
Obsidia was once a powerful sovereign of the Abyss who fell prey to corruption by the Dark God, losing her free will. She was betrayed by Alice and Thamuz, her allies, and cast into exile. After centuries of dormancy, she awakens, determined to reclaim her power and avenge herself — not just for vengeance, but to reassert her sovereignty and restore her rule in the Abyss. Her visual and thematic design revolves around bones, shadows, corruption, rebirth — very Abyss-centric.
Strengths
Very strong mid-to-late game once she has built up Bone Shards; her damage on single targets can become extremely high. Excellent at isolating and shutting down mobile heroes, thanks to her ultimate that cancels dash/blink/displacement on the target. Her passive lets her inherit item effects (lifesteal, slows, etc.), making her build flexible and her basic attacks potent. Good poke and lane pressure thanks to Skill 1, which helps with farming and shard accumulation.
Weaknesses
Struggles to escape when targeted by assassins or crowd control. Weak without abilities; basic attacks are not very strong. Can be taken down quickly by heroes with high explosive damage. Abilities may be easy to dodge or counter once opponents learn her patterns. Needs strong allies to maximize potential; struggles when alone.
Attack speed and critical damage
I choose this build because it gives obsidia high critical damage, life steal, and survivability. Tough boots for resistance, windtalker for attack speed and movement speed, haas' claw for life steal, Berserker's fury for high critical damage, Blade of Despair for high physical attack, and last wind of nature for attack speed and life steal and 2 second immunity in physical attack
Assassin emblem
I choose this emblem because it can boost obsidia's burst damage and mobility. Fatal increase her critical damage. Wilderness blessing increase her movement speed in river area. And lastly war cry to maximize her damage output in team fight
Battle Spell
Aegis is the best choice for Obsidia because it provides her with a strong shield during critical moments, allowing her to survive burst damage and continue dealing damage in teamfights. Use it when diving into fights or when being targeted by assassins to buy time for your skills and teammates to secure kills.
Obsidia
Early Game: Focus on farming and collecting shards/items to scale. Avoid risky fights since Obsidia is weak early and can be punished easily. Stick to lanes or jungle and secure gold. Mid Game: Start roaming and join small skirmishes. Use bushes with Wilderness Blessing (if chosen) to surprise enemies. Target squishy heroes and use her combos to burst them down quickly. Late Game: This is where Obsidia shines. With full items, she becomes a deadly carry who can delete priority targets in teamfights. Stay behind your frontline, wait for the right moment, and dive into the enemy backline. Use Aegis or Wind of Nature to survive burst and turn fights around. NOTE: obsidia is weak in early game
Best With Bane
Bane is compatible in obsidia because his AoE skills weaken and slow the enemies, making it easier for obsidia to burst them down. Together they can quickly secure objectives like Turtle and Lord, and their combined damage is deadly in teamfights.
Watch Out For Belerick
Belerick counters Obsidia because of his tanky nature and passive that reflects damage. Since Obsidia relies heavily on basic attacks and crits, she risks hurting herself against him. His crowd control also disrupts her mobility, making it hard for Obsidia to secure kills or escape.
