"You and nearby allies have added lightning damage per blue socket" enchant not stacking properly

I'm not entirely sure if this was intended as is, but this enchant only applies once, regardless of whether there are multiple copies of this weapon (via things such as animate weapon of self reflection).

It was tested through being in nearby range of an ally, and allowing me and an animate weapon of self reflection to get within buff range. Results are that either me or the animate weapon will apply the buff to an ally, but only once.

The wording of the enchant doesn't suggest that it only applies once, and the enchant is only really worth building around if the buff stacks.

Thank you very much.

i'm assuming you also only benefited from one instance of the "aura" then also from yourself and gained no extra from the animated weapons?

i was contemplating a chains of command version of this so this is good info to know beforehand...

the "crown of the tyrant" helm offers a similar buff but as with that you can only have 1 of each type stacked and not multiple same type, eg fire+cold+lightning = yes. fire+fire+fire = no.

Yes you can only benefit from one instance it seems.
I didn't know that crown of the tyrant also works like this, so that's interesting to know and maybe this socket enchant thing is intended?
Thanks for the information!

As a rule, the same buffs/debuffs don't stack in PoE. Only a few can, and usually it's somehow communicated to players.
