Viper the Netherdrake is a ranged agility Hero who can function as an excellent ganker and carry due to his slowing auto-attacks and his low cooldown ultimate. Although ganking is often made easier with Viper's presence, his true carry potential is revealed with sheer item power. Farming with Viper is relatively easy; while he has no area of effect abilities to clear waves, Nethertoxin makes last-hitting a cinch. However, active participation in ganking is very important before his ganking power wears out in mid-late game, due to enemy heroes playing more cautiously and obtaining better items. Poison Attack makes Viper very potent in hero harassing.

Bio[edit]

Viper Viper, the Netherdrake
Play "You've failed the acid test."
Role: Carry Carry / Durable Durable / Initiator Initiator / Disabler Disabler
Lore: The malevolent familiar of a sadistic wizard who captured and hoped to tame him, Viper was curiously glad to have been sprung from the sealed and unchanging subterranean Nether Reaches where his race had lived for millions of years, after tectonic slippage had sealed off the Netherdrakes in luminous caverns. Viper spent some time appearing to submit to the wizard's enchainments, hoping to learn what he could of the dark magics the mage practiced. But he soon realized that few spells were as deadly as the toxins that were his birthright. Exuding an acid that swiftly ate away the bars of his cage, the Netherdrake slipped free of his confines, spit poison in the old spellcaster's eyes, and soared out to let the world know that it had a new master.

Abilities[edit]

Poison Attack
Not blocked by Linken's Sphere. Does not pierce spell immunity. Play

Affects
Enemies
Damage
Magical
Intensifies Viper's venom, adding an effect to his normal attack that slows attack and movement speed while dealing damage over time.
Cast Range: 600 (Talent 675)
Damage per Second: 10/16/22/28
Move Speed Slow: 10%/20%/30%/40%
Attack Speed Slow: 10/20/30/40
Duration: 2
Cooldown symbol.png 0
Mana symbol.png 20
Does not pierce spell immunity. Slow persists and attempts to damage if debuff was placed before spell immunity and when not dispelled.
Modifiers
Debuff Poison Attack Slow: Dispellable with any dispel.
The Netherdrake's inborn toxic breath quickly drains the vitality of its afflicted.

Notes:

  • Casting Poison Attack manually uses the 600 (Talent 675) cast range. Attacking normally with Poison Attack on autocast uses Viper's default 575 (Talent 650) attack range.
  • Deals damage in 1 second intervals, starting 1 second after the debuff is applied, resulting in 2 damage instances.
  • Successive casts of Poison Attack on the same target do not stack, only the debuff gets refreshed.
  • The level 20 Talent talent allows Poison Attack to target buildings, damaging and slowing them.


Nethertoxin
Cannot be used by illusions. Disabled by Break. Pierces spell immunity.

Physical
Nethertoxin causes Viper's normal attack to deal bonus damage to units based on how much health they are missing. The bonus damage doubles for each 20% of health missing from the target. Nethertoxin deals half damage to creeps and buildings.
Base Hero Attack Damage Bonus: 3/6/9/12
Base Non-Hero Attack Damage Bonus: 1.5/3/4.5/6
Maximum Hero Attack Damage Bonus: 48/96/144/192
Maximum Non-Hero Attack Damage Bonus: 24/48/72/96
Poison from the Nether Reaches turns wounds into fatalities, and fatigue into death.

Notes:

  • Viper can lifesteal off the damage dealt by Nethertoxin and it is also able to crit.
  • Nethertoxin checks the attack target's health as the attack begins, not as the projectile is launched or hits.
  • This is how much damage Nethertoxin deals on each level against heroes (and non-heroes) at certain health percentages:
    • 100%–80% Health: 3/6/9/12 (1.5/3/4.5/6)
    • 80%–60% Health: 6/12/18/24 (3/6/9/12)
    • 60%–40% Health: 12/24/36/48 (6/12/18/24)
    • 40%–20% Health: 24/48/72/96 (12/24/36/48)
    • 20%–0% Health: 48/96/144/192 (24/48/72/96)

Viper exudes an infectious toxin that damages and slows any enemy that damages it in a 1400 radius. The acid exudate also increases Viper's resistance to magic.
Max Proc Distance: 1400
Magic Resistance Bonus: 10%/15%/20%/25%
Damage per Second: 10/15/20/25
Move Speed Slow: 10%/15%/20%/25%
Attack Speed Slow: 10/15/20/25
Duration: 4
Does not pierce spell immunity. Slow persists and attempts to damage if debuff was placed before spell immunity and when not dispelled.
Modifiers
Debuff Corrosive Skin Slow: Dispellable with any dispel.
It is not unusual for sword and shield alike to corrode in the very hands of those who attack the Netherdrake.

Notes:

  • Magic resistance stacks multiplicatively with other sources of magic resistance.
  • Increases Viper's total base magic resistance to 32.5%/36.25%/40%/43.75%.
  • The damage and slow debuff is applied to whoever damages Viper within 1400 range of him.
  • Corrosive Skin's damage has the no-reflection flag, preventing its damage from interacting with other sources of damage with the same flag.
  • Only reacts on the 3 damage types. Does not react on damage flagged as HP Removal.
  • Damage dealt by abilities that use an independent source of damage (e.g. Proximity Mines icon.png Proximity Mines, Death Ward icon.png Death Ward) does not trigger Corrosive Skin on the caster.
  • Deals damage in 1 second intervals, starting 1 second after the debuff is applied, resulting in 4 damage instances.
  • Successive procs of Corrosive Skin on the same target do not stack, only the debuff gets refreshed.

Viper slows the targeted enemy unit's movement and attack speed while also dealing poison damage over time. The slowing effect reduces over the duration of the poison.
Cast Animation: 0.3+0.53
Cast Range: 500 (Upgradable by Aghanim's Scepter. 900)
Damage per Second: 60/100/145 (Talent 140/180/225)
Move Speed Slow: 40%/60%/80%
Attack Speed Slow: 40/60/80
Duration: 5

Mana symbol.png 125/175/250 (Upgradable by Aghanim's Scepter. 125)
Upgradable by Aghanim's Scepter. Decreases mana cost and cooldown, and increases cast range.
Blocked by Linken's Sphere. Blocked upon impact.
Modifiers
Debuff Viper Strike Slow: Undispellable.
Once used to slay his sadistic summoner, the most powerful of Netherdrake infections spreads through the veins of those foolish enough to cross Viper.

Notes:

  • Viper Strike's projectile travels at a speed of 1200 and can be disjointed.
  • The slow decreases over time. Hit units regain 0.267%/0.4%/0.533% of their movement speed and 0.267/0.4/0.533 attack speed on each server tick.
    • This translates to 8%/12%/16% movement speed and 8/12/16 attack speed regained per second.
  • Deals damage in 1 second intervals, starting immediately as the debuff is applied, resulting in 5 damage instances.
  • Successive casts of Viper Strike on the same target do not stack, only the debuff gets refreshed.
  • The particle effects on Viper's wings during the cast time are visible to everyone, showing that the spell is being cast.


Talents[edit]

Hero Talents
+80 Viper Strike icon.png Viper Strike DPS 25 +20 Armor
+75 Attack Range 20 Poison Attack icon.png Poison Attack Affects Buildings
+16 Agility attribute symbol.png Agility 15 +15 Strength attribute symbol.png Strength

Notes:
  • Upgrading health increases maximum health capacity and keeps the current health percentage.
  • The armor and attack damage are added as bonus armor and bonus attack damage, and therefore do not benefit illusions.
  • The attack range talent also affects the cast range of Poison Attack icon.png Poison Attack.

Recommended items[edit]

Starting:

Early Game:

Core:

  • Power Treads icon.png Power Treads are the boots of choice to augment Viper's DPS and increase his tankiness.
  • Ring of Aquila (Active) icon.png Ring of Aquila is common choice for any agility core hero.
  • Dragon Lance icon.png Dragon Lance gives attack range and cheap stats, what is very important in mid-game.

Situational:

  • Hurricane Pike icon.png Hurricane Pike is a worthwhile upgrade from Dragon lance.
  • Shadow Blade icon.png Shadow Blade is a good pickup on Viper if you intend to use it for ganking. Viper is a very capable ganker if he can get into close range with a target. Between both of his slows and his damage scaling up as his target's health decreases, Viper is a very good hero for dueling.
  • Butterfly icon.png Butterfly is another item that provides a mix of damage and tankiness. Once you have a solid HP pool, evasion makes Viper much, much harder to bring down with physical damage.
  • Diffusal Blade 1 icon.png Diffusal Blade improves Viper's damage and gives mana burn. The active can purge enemies.
  • Mekansm icon.png Mekansm is a strong defensive item that is useful for both yourself and your team.
  • Monkey King Bar icon.png Monkey King Bar provides an unreliable disable on top of a solid chunk of damage. It's best if your team is low on disables or enemy carries are picking up evasion.
  • Aghanim's Scepter icon.png Aghanim's Scepter allows Viper to cast his ult it in teamfights more than once which lowers his target's DPS, slows them, and deals a hefty amount of damage. It also increases his tankiness, and Viper's usefulness goes up greatly the longer he's in a fight.
  • Manta Style icon.png Manta Style provides a mix of tankiness, damage, and chasing potential, all which greatly help Viper. It also provides a way to remove certain debuffs.
  • Orchid Malevolence icon.png Orchid Malevolence prevents spellcasters from using disabling spells, as well as making your targets more vulnerable to your DPS. The mana regeneration also remedies Viper's constant lack of mana.
  • Heart of Tarrasque icon.png Heart of Tarrasque increases Viper's tankiness, and combined with your Corrosive Skin and a Butterfly icon.png Butterfly, Viper will be incredibly hard to put down.

Trivia[edit]

  • Viper's response Play "Holy shit, it's me!" is a reference to a scene of the movie Top Gun.[1] Gyrocopter minimap icon.png Gyrocopter makes a similar, yet more accurate Play response upon meeting him as an ally.
