Poison damage and chaos damage

Does scaling Chaos Damage affect Poison damage? For example, from the passive tree or affixes on rings?

It doesn't increase the poison damage directly.

It helps if you are using gained chaos damage to apply the poison.

"When a unit is affected by Poison, they will receive 20% of the combined Physical and Chaos damage received as Chaos Damage over time for 2 seconds. The damage is affected by Ailment Effect and Magnitude.

The Chaos Damage received does not scale directly, but it can be scaled by modifying the Hit damage. Poison has a default stack limit of 1, but can be increased through modifiers, skills, or gems."

In simple words, chaos damage passives don't increase poison damage unless some or most of your damage (the hit) is chaos damage.

Different from POE1 where chaos damage does directly increase poison damage, at least last time I played.
