Steel bolts are the fourth available bolt, just after iron bolts. They may be fired by any crossbow. Steel bolts are created by using a steel bar on an anvil, requiring level 33 smithing. 10 unfinished steel bolts are created per bar. Most players find it easy to fletch bolts at the anvil south of Varrock's west bank because it is close to a bank and the Grand Exchange. One feather must be attached to each unfinished bolt to obtain a steel bolt, requiring a fletching level of 46. When feathering, each bolt yields 3.5 experience. Red topaz bolt tips can be attached to steel bolts to create red topaz bolts, requiring level 48 fletching.
