Something I found about Indi-Poison is that if you kill a white named mob with it's poison effect, you are not given the experience points for the kill. I'm not sure if this effect is intended or not, but it is a mechanic to take note of.
I found this out while I was fighting low level monsters. I figured it would be fun to gather 2-3 of em and aoe them down with Indi-Poison on, however I found out that even after engaging them if the monsters' names turned white on death they wouldn't grant any experience or items.
