Ever since BV got buffed, I theorycrafted on the possible BV builds and ofc, poison BV has always been a staple.
In this build, I tried to find a parallel to the popular nightblade poison builds and looked for an efficient way to scale spell poison.
I think this efficient method could be power charge stacking with Fenumus toxins. With a redeemer chest you could later even go badge of the brotherhood for another 30% more damage and better wither uptime.
On a side note: Cold iron point scales determination, defiance banner, herald of purity/agony.
60% more in the config is to account for the exponential scaling of the 48% more damage with gem levels.

the pob is probably a bit (actually a lot) inflated and e.g. the body armour is for sure not a starter body armour. So take it with a grain of salt, maybe together we can make this an actual build.
