Viper Strike of the Mamba

The new transfigured gem does not work as expected.

With a 0.22 second duration and an attack time of 0.4, I cannot apply poison on the second hit of my melee combo animation even though the first poison has already expired.

If I swing, release my mouse button, and immediately swing again, the second hit will poison as expected.

The skill is either bugged or I'm missing some obscure mechanic. I can clear fine but sometimes it just fails to poison.
I am using Alchemist's Mark so I can clearly see when the monster gets poisoned as it drops caustic ground (no, I'm not attacking faster than the mark's cooldown).
It's not caused by fast attacks because I can hold down the button or attack once every 2 seconds and still no poison is applied.
It's not because of me not being able to apply the poison due to some mechanic because I can swap to regular Viper Strike and it works immediately.
The problem is very apparent with bosses. Some I can kill and some just refuse to get poisoned no matter the attack pattern and I have to swap gems.

I have noticed the same thing, accounting for block chance, 100% accuracy and other such things I've still noticed that near the 'end' of one poison the skill will sometimes not inflict poison with over 100%% poison chance.

Not sure if it may be something to do with latency or whether it's just the inherent jankyness of strike skills.

This maybe is due to latency. Client side, the enyms has no poisen on them anymore (becasue it already expired), but serverside, it still is on. If you have a conflict between client side and server side, usualy the server side information is used (becasue client side information can be tampered with easier), so the enemy counts still as poisend.

I don't think it should be a latency issue. The situation described has my attack time at almost twice the duration of the poison, so I would think that the server couldn't mess that up as it would be impossible to hit again while the enemy is still poisoned.

how mutch attack time? how mutch latency? do the math.

It's in the original post that there was a 0.18 sec difference between the two. Normal ping is less than 50ms.

I got the same problem and recorded it. Attack time is 0.29 sec, poison duration is 0.14 sec and only every other attack poisons. I use the plague bearer buff effect icon so you can see when a poison is applied and life gain on hit works so I'm not missing.

I have the same issue as others have reported here. I have an attack time of 0.43 and a listed poison duration of 0.29 but only every other attack applies a poison if I hold down the attack key.
