A new poisons page has been made
A while back I found a page that was a great source for making and skilling up on poisons but the owner did not have it updated past level 80. Luckily, I was able to copy the script and add in the rows for levels 85, 90, 95, and 100. It is still missing a lot of trivial levels but it does show how to make all the poisons.
You can view the poison page here.
