Bowcraft/Fletching Bowcraft (or Fletching as it is called) is a skill where a player uses Fletching Tools to create arrows, bolts, bows, and crossbows. Crafting in the Britain Crafting Area will also have a chance to create "slayer" weapons. See the Slayer wiki for more details. Only Skill Scrolls are available for this skill.
