Arrows are always essential, but sometimes you need something more potent to take down your prey. This is where poison coatings come into play. They ruin the meat, but if you need something dead, they do the job. Poisons can either be brewed or, if you are brave, gathered. You strike me as the latter. The vipers by the pools to the south produce a powerful venom. If I have estimated you correctly, I think you could collect some of it.
