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.
|Viper, the Netherdrake|
|Play "You've failed the acid test."|
|Role:||Carry / Durable / Initiator / 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.|

- Poison Attack can be disjointed.
- Casting Poison Attack manually uses the 600 ( 675) cast range. Attacking normally with Poison Attack on autocast uses Viper's default 575 ( 650) attack range.
- Deals damage in 1 second intervals, starting 1 second after the debuff is applied, resulting in 2 damage instances.
- Can deal a total of 20/32/44/56 damage (before reductions).
- Successive casts of Poison Attack on the same target do not stack, only the debuff gets refreshed.
- The level 20 talent allows Poison Attack to target buildings, damaging and slowing them.
- The damage can be reduced with e.g. Enfeeble or Static Link.
- 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)
- 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, 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.
- Can deal a total of 40/60/80/100 damage (before reductions).
- Successive procs of Corrosive Skin on the same target do not stack, only the debuff gets refreshed.
- 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.
- Can deal up to 300/500/725 ( 700/900/1125) damage (before reductions).
- 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.
|+80 Viper Strike DPS||25||+20 Armor|

- 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.
- Tango helps Viper stay in lane.
- Slippers of Agility adds to Viper's last hitting ability in the early game.
- Circlet increases Viper's stats.
- Power Treads are the boots of choice to augment Viper's DPS and increase his tankiness.
- Ring of Aquila is common choice for any agility core hero.
- Dragon Lance gives attack range and cheap stats, what is very important in mid-game.
- Hurricane Pike is a worthwhile upgrade from Dragon lance.
- 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 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 improves Viper's damage and gives mana burn. The active can purge enemies.
- Mekansm is a strong defensive item that is useful for both yourself and your team.
- 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 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 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 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 increases Viper's tankiness, and combined with your Corrosive Skin and a Butterfly, Viper will be incredibly hard to put down.
- Viper's response Play "Holy shit, it's me!" is a reference to a scene of the movie Top Gun. Gyrocopter makes a similar, yet more accurate Play response upon meeting him as an ally.
