Slips in and out of skirmishes.
The only prisoner ever to escape from Dark Reef, Slark's abilities and ruthlessness are without equal. Pouncing into danger then slipping back out is what Slark does best. With every swing of his barnacle encrusted dagger, Slark steals his target's Essence, converting them to render himself more agile, striking harder and faster. He forges a Dark Pact, sacrificing his own lifeblood to dissipate negative energies that damage foes, and frees him from magical constraints. Concealing himself as he Dances through the Shadows, the Nightcrawler presents no visible target to would-be attackers. Hidden and Shrouded in this black haze, Slark escapes the inescapable and is always ready to to gut his enemies with little risk of retribution.

Slark minimap iconSlark, the Nightcrawler
▶️ "If I'd known I'd end up here, I'd have stayed in Dark Reef Prison."
Little known to the inhabitants of the dry world, Dark Reef is a sunken prison where the worst of the sea-breed are sent for crimes against their fellows. It is a razor barbed warren full of murderous slithereen, treacherous Deep Ones, and sociopathic meranths. In this dim labyrinth, patrolled by eels and guarded by enormous anemones, only the vicious survive. Pitched into Dark Reef for crimes unknown, Slark spent half a lifetime without kin or kindness, trusting no one, surviving through a combination of stealth and ruthlessness, keeping his thoughts and his plans to himself. When the infamous Dark Reef Dozen plotted their ill-fated breakout, they kept their plans a perfect secret, murdering anyone who could have put the pieces together--but somehow Slark discovered their scheme and made a place for himself in it. Ten of the Dozen died in the escape attempt, and two were captured, hauled back to Dark Reef, then executed for the entertainment of their fellow inmates. But Slark, the unsung thirteenth, used the commotion as cover and slipped away, never to be caught. Now a furtive resident of the carnivorous mangrove scrub that grips the southern reach of Shadeshore, Slark remains the only successful escapee from Dark Reef.

Root Notes:
Getting rooted while already leaping does not cancel the leap.

Essence Shift icon Essence Shift must be drafted as well for it to get applied.
Time in the Dark Reef made Slark a dangerous assassin; aggressive and fearless.

  • Leaps at a speed of 933.33 (Upgradable by Aghanim's Scepter. 1333.33) for up to 0.75 seconds.
    • Does not disjoint projectiles upon cast.
  • Pounce has the following leap mechanics:
    • Always leaps toward the direction Slark is facing. Does not lock Slark's facing angle during the leap.
    • Always leaps the full distance, unless an enemy hero gets within 120 radius of Slark during the leap.
    • Moves Slark upwards over other units and over impassable terrain.
  • Slark can turn and cast abilities and items during Pounce, but cannot attack.
  • With the maximum distance and latch radius, Pounce can latch on enemy heroes up to 820 (Upgradable by Aghanim's Scepter. 1120) range away.
    • Can only latch on heroes and clones. Does not latch on illusions and creep-heroes.
    • Can latch on invisible units, but not on invulnerable or hidden units.
    • When latching on a unit, Slark is automatically ordered to attack the target.
    • Pounce first applies the leash debuff, then apply 0/1/2/3 Essence Shift icon Essence Shift stacks based on its current level.
    • Essence Shift notes fully apply. If it is not learned, no stacks are applied.
  • Stops the enemy by slowing their movement speed.
    • The slow gets exponentially stronger towards the edges of the 120 leash radius.
    • This effectively causes the target to come to a halt if the leash is stretched too much.
    • The slow is only present when facing away from the center. The target is not slowed when facing toward the center.
    • Since the slow is fluctuating a lot, it is not displayed in the HUD.
  • Destroys trees within 100 radius around Slark upon landing.
  • Pounce cannot be cast during Pounce. During the leap, Pounce is on a non-refreshable cooldown which is bound to the leap buff.

  • Slark is named after a rare murloc in "World of Warcraft".
    • His murloc heritage was completely removed in the transition to Dota 2 to avoid copyright issues, since the murlocs are an existing race in the Warcraft universe.
  • ▶️ "Met you once, cut you twice." is a reference to the carpentry phrase "measure twice, cut once.".
  • ▶️ "Griefer madness..." is a reference to the propaganda film Reefer Madness.
    • As well, a griefer is a role a player assumes while in a multiplayer game to deliberately irritate other players.
  • Slark's weapon, a shiv, is the traditional prison weapon and is a reference to his backstory.
