Viper specializes in pinning down single targets from a distance, while dealing moderate damage. His Poison Attack allows him to consistently slow someone down, and he can fire a heavily concentrated Viper Strike toxin to nearly stop someone in their tracks, and deal good damage over time. This allows him to be more aggressive as he can go in and keep targets from escaping. To aid with leading a charge, he's developed Corrosive Skin that offers resistances, returns minor poison and slows the attacker. While most of Viper's damage is dealt over time with poisons, he has a passive Nethertoxin which allows him to deal additional damage to weaker units.

A malicious Drake tamed by the Lich King himself, Viper is a fierce, acid-spitting beast whose speed and agility surprises the most hardened of warriors. Cursing himself into a maddened rage, Viper charges into battle without regard of his own safety. His salivary glands produce stinging poison that causes enemies to writhe in pain, severely damaging their nerves. Be careful when facing this powerful monster...its dark silhouette may be the last thing you will ever see.
