Poison with Spells Mechanics Question (Herald of Agony)

I put two points into Chance to Poison with Spells. 10% and 15%.
I have a Herald of Agony active.
Why isn't my Purifying Flame spell causing poison damage to activate Virulence for the Agony Crawler?
If I have at least a 25% chance to poison with spells (and I wipe out packs) why isn't Agony being triggered when these two passives supposedly grant poison?

I just tested the interaction of Herald of Agony and purifying flame to gain virulence and it worked 100%

If you unprivate your profile I could investigate further.

To apply a poison, a hit have to deal phys or chaos damage (by default).

I think your Purifying Flame is full converted to elemental damage.

I gave up trying to find where the conflict was and respec'ed out of Poison with Spell Damage.

It must have been a conflict somewhere based upon my build.

LoL- I'm broke on Orbs of Regret, or I would reassign the two points, make my profile un-private, and let you find the culprit.
I've had luck with Herald of Agony before when I'd equipped certain poisoning items.

I suppose I'll have to take a real close look at what I've done wrong.

Yeah I'll have a look.

Need to see your characters first. Go to your profile page > Edit privacy settings > then untick 'Hide characters tab' and then update at bottom.

This is it.

You're converting all to elemental (50% on gem, 50% phys to lightning support).

Good luck

I think that fixed it!
Although with only 28% chance at poisoning with spells the virulence stacks much slower than if I stack a Consuming Dark dagger.
Thx for the help.
