Poison is unique in the way it works, as unlike ignite or bleed, it can stack. That means modifiers that affect strictly hit damage (like %Increased damage with hits) won’t affect it in any way.
It deals chaos damage over time, and its damage is based on base physical/chaos damage of the hit that inflicts it. Poison is the chaos-based ailment (type of debuff) found in PoE.
Out of all the poison-designated skills, it’s certainly in the top 3 when it comes to clear speed.Ĭobra Lash = Unbound Ailments = Vicious Projectiles = Added Chaos Damage = Deadly Ailments = Vile Toxins/Greater Multiple Projectiles Poison builds are vastly different from your regular PoE builds - they don’t really scale the damage your hits deal - they instead stack ailment/poison damage increases and base chaos/physical damage. Cobra Lash is one of the skills that were tailor-made for poison.
