Amanamu's Gaze and Minion's poison DPS

Does anyone know if Amanamu's Gaze should increase minion's Poison DPS?

I am using PoB community and the jewel is available but the minion's poison DPS doesn't increase when I equip Amanamu's Gaze. I am using other ghastly eye jewels as it is the condition necessary.

If the jewel affect minion's poison but it is not showing the DPS on PoB, how would I calculate the DPS increase myself?

thanks

Amanamu's Gaze
+(5-10) to all Attributes
Minions have +6% to Damage over Time Multiplier per Ghastly Eye Jewel affecting you, up to a maximum of +30%

By description, it should totally increase your Minions' DOT Multiplier (infernal legion, specter's skills like Unrighteous Fire and Winter Cloak, Bleeding, Corrupting Blood...), which includes poison inflicted by Minion's hits.
Abyssal jewels should always affect you, even if white, as long you don't socket them in a shield while having Necromantic Aegis.

I'd blame PoB this once. Sometime they need some patches in order to make new uniques work as intended, or at least expected.

Along the same pages do we know if you stack Amanamu's Gaze Ghastly Eye Jewel if you get 30% per a just the 30% max regardless?

I believe Purposeful Harbinger may help us in here.

The new text says:
"Aura Buffs from Skills have 8% increased Effect on you for each Herald affecting you, up to 40%"

The original text was:
"10% increased Effect of Auras on You for each Herald affecting you"

We know the first text stacks, up to a certain maximum cap (40%), while the second will stack limitless.

I belive Amanamu's text is more in line with the former than the latter, so I'd expect multiple Amanamu will only help you reach before the 30% threshold.

Of course empyrical test may disprove me

Its a PoB error the line shouldn't be blue it should be red to indicate it doesn't function currently

As to its effect just multiply your minions poison damage by the value stated AFAIK there aren't any other sources of damage over time multiplier available for minions - maybe some from quality of specific supports.

Edit: Reddit is fairly convinced that its a global cap so no stacking multiple of them, apparently unique worded in this way are hard caps and enough people have agreed that I probably trust the answer.

Thanks for the replies

Edit: figured it out! :)
