Focus on poison proliferation using Bino's Kitchen Knife with Viper Strike, employ elusive stacking for survival and damage, and optimize Wither application methods for maximum damage output in Path of Exile 3.28.
Core Build Mechanics
The Nightblade Viper Mamba build excels in Path of Exile 3.28 due to its ability to leverage poison proliferation with Bino's Kitchen Knife and critical strike scaling through elusive effects. Bino's Kitchen Knife received a notable buff this league, increasing its poison proliferation range, which synergizes effectively with Viper Strike and Penance Mark. Penance Mark allows you to spawn phantasms that apply poison to enemies, which is then proliferated further by Bino's.
The build also relies heavily on elusive stacking, which not only amplifies critical strikes and poison damage but also provides substantial defensive benefits like increased evasion and movement speed.
