OK, so I did manage to make poison weapon attacks and an NPC to test that, but the NPC required me to attack him before he would show aggression, and the poison weapon attack appears to not be attached to that NPC. I will have a look at falmers to see how they have their poison weapon attacks attached to them. I'll post more when I find it.

I tried to make the new NPC attack, but all he does is sit there or fuck people. He forced himself on my PC twice, and a dead dude once.

I attacked him to test the poison weapon spell I added to his spell list, but he doesn't use it. Maybe because it's a spell, and he is set for archery, he won't use the spell. I need help on this.
