The great thing about survival is knowing how to use the environment to your advantage including the ancient tricks of purifying water such as the survival skill, a small metal bowl with a larger metal bowl with a small run off catch can purify water pretty easily over a fire of any kind not to mention there are convenient things that having an animal along can help with such as finding water.<br/><br/>While none of these are guaranteed it should be noted that they are unlikely to fail on a repeated basis, but water reserves should be kept up, food is easy with survival and archery in a ranger.<br/><br/>I think mostly what we'll need will be supplies for crafts like archery and things of that nature, along with the inks needed for warding.
