Forum:Poison sphere and it's chance to inflict poison

Poison shiv, Demon Rifle, Vine Lance, etc.

Does anyone know the chance for poison to be inflicted on an enemy with the poison sphere (poison shiv) equipped? Also, does the chance of poison infliction increase with the number of hits that unit registers? In other words, would the chance of poison infliction be higher if equipped to a Gun King Douglas who hits multiple times per attack, as opposed to a high elf who only hits the enemy once? I would assume the developers didn't take this into consideration, but it would make some sense to have a higher chance. And this question should apply to the other spheres which cause weakening, sickness, injury, and paralysis.
