Poison build

Has the poison built been edit or Adjust it. Because I can't figure out what to scale poison skills
with it. I try to increase the chaos damage, but it doesn't change. How much the poison does the only thing I know for cern is the magnitude one, that's the only thing I can see they're doing damage.
And physical, but it's not being affected by chaos at all. I've been asking around. But I can mix information, is there any way someone could tell me the correct way

Poison damage is based off damage from the hit triggering poison. Only damage from the hit that is physical or chaos damage contributes to the magnitude of poison inflicted. You can scale poison damage magnitude by scaling chaos damage, but only if the hit is dealing chaos damage. For most martial weapons this requires using a support gem to change damage applied to chaos damage.
