Tracking bolt is a craftable ammunition item in The Witcher 3: Wild Hunt that can be purchased from the following merchants:
- Blacksmith in Oxenfurt
- Zoltan Chivay during The Battle of Kaer Morhen, if he is recruited
- Smith during the "Witcher" epilogue, if Redania wins the war
Crafting Requirements 
Min. Required Level: Amateur blacksmith
Some arbalist enemies may drop small stacks of these, and stacks of up to 10 have a 50% chance to appear on some soldier corpses (all may also have exploding bolts):
- South of Lindenvale's cemetery, under the northern side of the bridge
- In the middle of some rocks on the fields between the two converging roads southeast of Benek
- In Ignis Fatuus' cave, right next to the chest with Diagram: Ursine silver sword - superior
- Under a tall flag in the marsh northeast of the Seven Cats Inn
- In the woods far north of Est Tayiar, edge of the base game map, but shortly west of Vikk Watchtower with the Hearts of Stone expansion
- In the ruins right in the middle between Holmstein's Port and the Cave of Dreams

- The crafting screen will show these to have level 8 required and 0.01
, but any crafted tracking bolts will have a level requirement of 1 and 0.06 . While not erroneous per se, "+6 Piercing damage" will also be shown as an effect instead of the inherent base damage on the bolts, which actually ends up as "5-7 Piercing damage".
