  • Big MT cazadores can be found in and around the Z-14 Pepsinae DNA splicing lab, including the unique variant Specimen 73. The normal cazadores re-spawn every 3 in-game days.
  • If cazadores aren't respawning but previous bodies are still showing up at the facility and surrounding area, removing the poison glands then waiting three days in the Mojave should make them spawn again.
  • This perk complements Implant C-13, giving a potential +40% bonus to damage against cazadores.
