Siphoning Attacks working reverse of how it says, apparently

Mystrius_Archaion

Siphoning Attacks is supposed to provide healing when you hit an enemy with a light or heavy attack.
I've been testing it with combat numbers turned on for healing incoming and outgoing and just incoming with no other buffs or passives or other heal abilities active. I've been testing on a troll since they're little threat to me and durable enough for good testing while also allowing heals to show. I am using a lightning staff, hoping it heals on each tic.
My tooltip says "causing your light and heavy attacks to heal you for 1568 health".

Here is where it gets weird.
The troll gets me down to 30% health as my threshold to start attacking. I've been using Siphoning Attacks the entire fight just passively keeping it active without any healing incoming. When I start attacking, I usually see a heal on the first strike and apparently the last hit sometimes, not always. This inconsistency prompted me to try just hitting one light attack and seeing if it would heal every time, which it did, but I also noticed that when the troll struck me it also healed with the green number inside parentheses, like (2420), with the number not matching the tooltip. It seemed to behave like a "every time you hit an enemy with a light or heavy attack, for 5 seconds, you heal each time you are struck by that enemy" instead of a "heal on attack".

I'm not sure how Siphoning Attacks behaved before it was changed to the current behavior, even though I know it was different, but it definitely seems severely bugged right now. It doesn't behave like the tooltip says.

Can anyone else confirm this? Does anyone know the old info for Siphoning Attacks?

After further testing, it seems to be some sort of buff that only lasts for the 3 seconds or the expected duration of a full heavy attack and only heals on the first tic and any incoming hits within that 3 seconds, even when the siphoning attacks buff expires just as the heavy attack is started.

This definitely is wrong.

Channeled attacks (like lightning staff heavy) were changed recently. It was done to prevent things like shield breaker set bonus proccing on every tick of the heavy attack. Instead shieldbreaker now only hits once pre heavy attack, no matter how many damage ticks it does. I suspect siphoning attack got affected as well, and only heals once per heavy attack, despite it's many 'hits'. Thats why you see siphoning proc reliably on light attacks(they only do damage once per cast), but not heavy attacks(many damaging ticks, but only one heals you).

Green number inside parentheses means your shield absorbed the attack. (2420) means you got hit for 2420 damage, but the damage got absorbed by your shield.

Ohhhhh, that explains the green numbers in parentheses, but the only shield I was using was a legendary hardening enchant and I saw back to back numbers over 2k often when I know my hardening shield is only supposed to be 3290, so that's odd.

Sadly, Siphoning Attacks doesn't heal for the value the tooltip says, or more as it should considering buffs. It seems to always be less.
But thanks for the clarification on why I was seeing some odd behavior. It would be nice if it did heal for every tic of a heavy attack, which seems to be once a second or slightly faster anyway, as it would encourage heavy attacking which they have been trying to push anyway.
Oh well.
