Primal Arrows are made at the Arcane Workbench.  They can be made with any of the primal shards, and each type provides a different elemental attack against the target:

  • Air: Bypasses armor protection.
  • Fire: Deals fire damage (instead of normal damage), and sets targets afire.
  • Water: Inflicts slowness (chill).
  • Earth: Extra damage.
  • Order: Slightly less damage, but inflicts weakness.
  • Entropy: Slightly less damage, but inflicts withering.

If fired from a bow with the Infinity enchantment, they have only a 1/3 chance of not being used up.
