So, the party ninja is a poison user and is wondering if there is an item or a spell that will allow them to duplicate a very strong poison, the idea behind it is the poison is very rare and expensive and the party doesn't want to have to find or make more of it. Ive been trying to google the answer but cant seem to find anything, however i remember reading about an item that can duplicate what you pull out of it, (i think it was a bag) but that was awhile ago and I may just be imagining things. Any help would be greatly appreciated.
