Viper wins by attrition: Poison Attack stacks a slow and strips magic resistance, Nethertoxin grows stronger the longer a target stays inside, and Corrosive Skin punishes anyone who hits him. Break stops Corrosive Skin from applying, apart from the Nosedive version. Viper Strike pierces spell immunity, so leaving the toxin early matters more than immunity.
Counter items
Silver EdgeBreak prevents Corrosive Skin from slowing and damaging attackers.
Black King BarBlocks Poison Attack and Nethertoxin, though Viper Strike pierces it.
