Ahh... the Wildy is full of blood and sweat, I keep losing my appetite but I have to eat at low health still, right? sometimes at least. So, I'd just bring some perfume. Eih, killing should be fun, right?
If I was taking one real world item into the wilderness it would a Bombardier-Sea Doo ATV, its quick steering action to dodge missiles, reliable acceleration for those quick getaways, and the blinding effects of dirty-sand spitting halts, and re-fueling this would be a beard tickle to dwarven inginuity.
