Is there anywhere an overview how difficuolt it is to create a specific toxin/drug with the chem-use sub-skill of medicae ?

Would it make sense to give each such substance a remark, how difficult crafting it would be ?

Furthermore...is it correct that there are very few poisons listed at all in the rules ?

Edit: ignore this post

For poisons I use the short appendix in the back of the booklet that came with DH1's Game Master's Kit. The booklet is the adventure "Maggots in the Meat" and there's two pages in the back entitled "Rules for Poisons & Toxins". It also includes a list "Infamous Poisons of The Calixis Sector".

The whole section is just two pages but I think it basically gets the job done.

Would be two good pages to get overworked and integrated. Toxins are very important for an assassin.
