[2.1.0] - Bear trap bino's proliferation

Pros:
Reasonable damage output
Huge amount of regeneration on kill (immune to anything but one shots)
Can spread multiple poison stacks to bosses
Moderate amount of life (160-170%)
Powerful blasphemy'd curses (makes you decent in parties)
Bear trap scales from trap throwing speed/trap damage, so very simple to gear
Completely reflect immune

Cons:
Bino's proliferation range is rather small
Besides curses, no other major defenses
Curse immune maps and mobs
Still get affected by corrupted bloodline mobs

The next option for the build would be to drop the unique shield (when bear trap hits 20), replacing it with a 5 link chestpiece and possibly run hidden potential if I am running out of damage

Whenever you throw a bear trap, that trap hits a mob and inflicts a high strength poison effect (scaling from physical, trap damage and vulnerability). Because Bino's kitchen knife only proliferates the poison on enemies YOU kill, Southbounds prevent the initial hit from killing a mob. The poison then kills the mob (that usually has 1 life remaining). Since (for some reason) damage over time inflicted by traps, totems, and mines is attributed to the player instead of the trap, totem or mine Bino's then proliferates the poison. This is the reason why players using Flame Totem will sometimes activate their herald of thunder (which is a buff that requires the player to kill an enemy). Bino's then proliferates that poison in a small radius around the dead mob, causing a chain reaction.

Vulnerability: vulnerability double scales both the hit and the dot, making it extraordinarily powerful with significant curse effect.
Temporal chains: In addition to be a powerful defensive option, temporal chains also significantly increases the duration of the dot (other effects expire 61.6% slower) thanks to the curse effectiveness
Bear trap: Bear trap doesn't scale with spell, attack or elemental damage making gear requirements easier and making the skill have ludicrous base damage.

Temporal chains - Vulnerability - Enhance - Blasphemy
This, in combination with your 44% curse effect, is your bread and butter defensively and offensively. put this in a +1 all item if you can. It's worth noting that a catarina shield with a +1 to all gems corruption increases the level of your enhance by 2 (who the hell needs atziri's disfavour!). If you get very lucky, that'd be a better choice than Geoffrey's or the Vertex.

Bear Trap - Poison - Trap and Mine damage
This 3 link is the core damage setup. There are a number of supports you can add, listed with their strengths below

Increased duration - Increases overall damage and pin duration by alot, but requires time to work
Hypothermia - Multiplies both the hit and the dot, making this an exceptionally powerful damage support. Requires chilled ground (arctic breath gmp chain and arctic Armour would make this very easy).
Void Manipulation - Multiplies the dot. Reasonably strong, and what I'm using atm.
Rapid Decay - Similar to Void manipulation, but reduces the poison and pin duration. I'd use void Manipulation first.
Added fire - Increases our hit, but as fire damage. The fire damage cannot poison, making this solely a single target option (and a terrible one at that). Not worth it at all.

Abbysal cry/Rallying cry - Rallying cry gives significant damage and mana regen (something that is very nice to have) while Abbysal cry gives very good AOE damage (especially with increased AOE, void manipulation, and poison supporting it). Abyssal with reverse knockback would be very interesting, but the build needs the southbound gloves.

Golem - I personally chose flame golem, as the damage bonus double dips. it's worth noting that the bino's regen will heal him too!

Fill in he rest of your links and sockets with whatever you think is appropriate. Maybe a cwdt setup or something?

You can see the gems I'm using in the gear linked. I'm currently running enfeeble, temp chains, and vulnerability, all on generosity which makes the build quite the team player.
It's worth noting that the temp chains slows by 47% * 1.54 = 72.38%.
Enfeeble'd do pretty much the same thing to accuracy if I went the mile.
