Once dried, the Green Birch Sapling will become a Cured Birch Sapling and will appear to be a more dull brown color. The cured sapling can then be used for crafting Arrow Shafts. Both Green and Cured Birch Saplings never Decay, and will always be at 100% Condition.
The player can use a Hunting Knife or Hatchet (or their improvised versions) to craft a cured birch sapling into 3 Arrow Shafts at the Work Bench.
