FFXI HorizonXI - Treasures & Tribulations BCNM - BST/WHM

First time doing it so I made some mistakes. I went for the large chest based on some comments I read on discord so next time I'm going to try small chest because I've also heard that one recommended. If I can do it with just 1 jug + 1 reward that would be optimal. /WHM seems pretty vital to removing the poison unless you stock up on like a stack of antidotes.
