Dirty Techniques Poison Not Working???

So i got Dirty Techniques from the passive node:

10% increased Skill Effect Duration
40% increased Damage over Time
25% chance to Poison on Hit against Bleeding Enemies

Now i'm not sure why but for some reason it won't proc, i'm going bleeds on my class.
You can check my character profile for how i'm running things and with what skills/nodes but i swear it ain't procing and i have no idea why. :(

Any idea as to why? Am i doing something to negate it?

Thanks :)

Both poison and bleed scale off initial hit. physical and chaos damage can apply poison, bleed is based on physical attack hit damage (and unlike poison cannot stack, only the most potent bleed is active)

The problem of your character is not proccing poison (Im pretty sure it procs) but that damage your weapons is pitiful. Weapons you use are good for very early leveling, but not at lvl 43. Also the chance to even apply poison is small. How no idea how you managed to get past A4 normal:)

The tree, well, this is not how you do a build in PoE. It is a result of misunderstanding how bleed and poison work. Most of the chars showcased here can be fixed but this seems like reroll.

Also, linking two support gems of one kind does not work, lower level one is ignored.
