Viper counters & matchups
Viper is an anti-carry lane bully whose Poison Attack slows movement and attack speed, Corrosive Skin tanks magic, and Viper Strike cripples a target. He hard-counters attack-reliant and sustain heroes: Huskar (57.3%) loses to the attack-speed and heal reduction, while Gyrocopter (56.2%), Timbersaw (56.0%) and Templar Assassin (55.2%) get out-traded. Viper is countered by illusions and scalers his single Strike can't handle: Phantom Lancer (41.9%) and Naga Siren (44.1%) out-body him, while Spectre (44.7%) and Wraith King (44.7%) out-scale/tank. Draft tip: Viper is a brutal anti-carry/anti-Huskar lane and pickoff core into physical drafts; he's weaker into illusion comps and late-scaling hard-carries.

Viper synergies
Viper's Poison Attack and Viper Strike cripple the enemy's top right-clicker and his Nethertoxin chunks through fights — he's a strong anti-carry frontliner. He pairs best with scaling and durable cores: Spectre (55.5%) and Wraith King (54.9%) farm behind his lane dominance, while Night Stalker (53.1%) hunts the targets he slows. Give Viper a hard-carry to protect and his slows neutralize the enemy's damage dealer every fight.
