Viper, the Netherdrake, is a ranged agility hero who can function as an excellent nuker, ganker and carry due to his assortment of low-cooldown spells and debilitating auto attacks. Farming with Viper is relatively easy—Nethertoxin makes clearing creep waves and neutral camps a cinch—and combined with Corrosive Skin, he becomes a formidable tank with high damage output; Poison Attack and Viper Strike ensure he can whittle down even the most impervious targets. In particular, Viper excels against lineups that rely on magic damage in the early-midgame. However, he needs to actively participate in team fights before opponents can afford items to counter his spells and exploit his weaknesses. Between talents, the special properties of Nethertoxin, and Poison Attack, Viper can retain his power far into the late game.
- Casting Poison Attack manually uses the 600 ( 700) cast range. Attacking normally with Poison Attack on autocast uses Viper's 575 ( 675) attack range.
- Deals damage in 1 second intervals, starting 1 second after the debuff is applied, resulting in 3 damage instances.
- The damage is based on the target's current to maximum health ratio. For each percentage of missing health, the damage increases.
- For example, a target with 400/1000 health will take 15/30/45/60 damage on the next tick, since it is missing 60% health.
- Successive casts of Poison Attack on the same target do not stack, only the debuff gets refreshed.
- The attacks first apply the debuff, then their own damage.

- Can deal up to 160/240/320/400 damage to a single unit (before reductions).
- The damage of multiple instances of Nethertoxin fully stacks. The magic resistance reduction, however, does not.
- When leveling up the ability, the magic resistance reduction value on already affected units does not update to the new value.
- However, if an enemy receives the debuff after leveling it up, that enemy receives the new magic resistance reduction value.
- The damage value does not update and is always based on the level the ability was cast on.
- 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% ( 37%/40.75%/44.5%/48.25%).

- 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.
- 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 5 damage instances.
- Can deal up to 300/500/725 ( 800/1000/1225) damage (before reductions).
- Successive casts of Viper Strike on the same target do not stack, only the debuff gets refreshed.

|Roles:||Carry Durable Initiator Disabler|
|Playstyle:||It was foolhardy to try and tame a Netherdrake, a lesson the old wizard learned in death. Freed from his captor, Viper spread his wings and went forth to explore the surface world. His Poison Attacks cause joints to harden, crippling foes whether they choose to flee or fight. Nethertoxin spreads throughout their body, sapping the will and weakening the spirit. The Netherdrake's tough, Corrosive Skin protects against spellcraft, and burns assailants with acid. But it is the dreaded Viper Strike that signals the beginning of the end. The afflicted victim staggers to a crawl, barely able to take his next step. If the Netherdrake doesn't finish him off, the venom in his veins will.|
