Mort's a champ for implementing this, and I love being able to really run with the poisoner vibe, but at the risk of looking a gift horse in the mouth, I think some of the poisons harvested could use a bump up in DC. I can't say I've tested poisons harvested from everything in the server, but I believe there's no difference in DC from the quality of venom harvested. Weak, Potent or Superior Scarab Venom all has a DC of 14, which seems on the low end of the scale compared to some of the other poisons you can find.
