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 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.

- Can deal up to 240/360/480/600 damage to a single unit (before reductions).
- Multiple instances of Nethertoxin's debuff do not stack.
- When leveling up the ability, the magic resistance reduction and damage on already affected units do not update.
- However, if an enemy receives the debuff after leveling it up, that enemy receives the new magic resistance reduction and damage values.
- Choosing the talent which adds the silence immediately updates all already existing debuffs.
- Magic resistance stacks multiplicatively with other sources of magic resistance.

- 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).

|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.|
