For hunger: it's okay to eat sooner. Instead of saving food focus more on trying not to waste turns, which often means picking your fights, leaving equipment behind instead of going back to sell etc.

Faith is my armor: try not get hit, think about positioning, don't get yourself surrounded. As a warden: bow is great but it doesn't have to be your only weapon, especially in the beginning you won't be able to kill all the crabs with 0-2 damage shots. Use grass and plants.

Did you know that 99.7% of players die holding onto equipment that could save them?
