As you progress, death becomes less and less likely in the game. You got a little unlucky, 80 hp isn't a whole lot to go out into the black forest with (let alone the swamp).

I would be more than happy to help you get your stuff.

Higher level Food currently in game can get you up near 260 health (so there is hope, something for you to shoot for)

Look for carrot seeds in black forest, and turnip seeds in swamp. Once you harvest them you'll have access to the soup recipes. Also, Blueberries and Rasberries make queen's jam, another good food to have.

if you died from poison in the swamp, there is a poison resistance potion that decreases poison damage by I think 75% (someone will correct me if I"m wrong).

If you don't think it will ruin your experience I can bring materials in your world to craft a long boat which will give you some added protection against threats you'll face on your journeys.

Just send a friend request if you are interested.
