The Netherdrake's inborn toxic breath quickly drains the vitality of its afflicted.
- Modified values: None.
- 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 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.
Slow persists and attempts to damage if debuff was placed before spell immunity and when not dispelled.

Nethertoxin
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.
Details
- Modified values: None.
- The bonus damage is dealt in one instance together with the attack damage, and counts as attack damage as well.
- It can be lifestealed off of, and is considered by crit or cleave.
- It is not affected by percentage-based attack damage bonuses or reductions, but can be reduced with flat reductions.
- Nethertoxin checks the attack target's health as the attack begins, not as the projectile is launched or hits.
- Works against every enemy unit, including buildings and wards. Treats creep-heroes as creeps.
- 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%

It is not unusual for sword and shield alike to corrode in the very hands of those who attack the Netherdrake.
- Modified values: None.
- 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.
- Does not affect buildings, wards or invulnerable units.
Slow persists and attempts to damage if debuff was placed before spell immunity and when not dispelled.
Corrosive Skin Slow
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.

Once used to slay his sadistic summoner, the most powerful of Netherdrake infections spreads through the veins of those foolish enough to cross Viper.
- Modified values: None.
- Viper Strike's projectile travels at a speed of 1200.
- The slow decreases over time. Hit units regain 0.3%/0.4%/0.5% 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 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.
