Passive Tree, Ascendancy, and Keystone Highlights

Overwhelming Toxicity - Doubles the number of poisons that can be applied simultaneously.
Contagious Contamination - Spreads poison to nearby enemies on kill.
Escalating Toxins - Increases poison duration based on recently inflicted stacks.
Chaos Inoculation - Grants immunity to chaos damage and bleeding, but reduces max life to 1. This pairs well with evasion and ES layers.
Wither Away - Boosts withered effect magnitude by 20% and applies Wither to nearby enemies.
Pure Chaos (via From Nothing jewel) - Converts 100% of damage into extra chaos damage.
These nodes ensure poison not only applies quickly but scales into devastating levels of single-target and AoE damage.
