People do not follow you in combat. They go where you click them to go. Only outside of combat do they follow you (and it is possible to disable that). So why would you need to walk in poison with your party outside of combat?
The problem is not this talent, the problem is you not understanding basic game mechanics.
You are quite rude, aren't you? Yes, he does follow me into combat. He is controlled by my friend. I have literally no control over him. What, do you think I've been poisoning myself the whole time? After getting zombie on half my party? And then building a build to escape myself?
