Viper Strike

Viper Strike is a claw / dagger / sword melee strike attack skill. It hits the enemy, converting physical damage to chaos damage, and applies poison, dealing chaos damage over time based on the combined physical and chaos damage dealt. It uses both weapons to deal damage if you are dual wielding.

Skill functions and interactions

Viper Strike applies poison with a 4-second duration on hit. Viper Strike specifically overrides the base poison duration with its own base skill duration. IncreasedDuration Increased Duration Support, ReduceDuration Less Duration Support, UnboundAilments Unbound Ailments Support and SupportRapidDecayGem Swift Affliction Support all affect the duration of that poison.

Some beneficial curses and auras for Viper Strike include Despair Despair, TemporalChains Temporal Chains and DeliriumGem Malevolence.

Viper Strike is a Strike attack, thus:

Multistrike Support allows to automatically target nearby enemies for two additional strikes. Note that even though this support gem lessens attack damage, poison does not scale from attack damage modifiers.
Melee Splash Supportcauses Viper Strike to hit enemies around the initial target, poisoning each.
Ancestral Call Support , Strike Skills target an additional nearby Enemy prefix modifier on hunter-influenced gloves, and annointable passive Tribal Fury all work with Viper Strike.
