Bat’s Blood Oil:
Daemonorops Draco (Modern Dragon’s Blood)
Dracaena Cinnabari (True Dragon’s Blood)
Used for curses/enemy work, also for pacts, and an ingredient in the Elixir of Manifestation. Remember to always get 100% essential oil, not “fragrance oil,” also when buying online, look out for fragrance oils by the company “Essential Trading Post,” cleverly injecting their company name in the product titles to trick people into thinking their product is Essential Oil.
Keep in mind, most “Bat’s Blood Oil” sold online is going to be lacking Magnolia oil and obviously, the blood of a rat. This is Dragon’s blood oil. Dragon’s Blood Oil + Magnolia and Rat’s Blood = Bat’s Blood Oil. Also, Cinnabari is much more potent, although much more rare and hard to come by, than Draco.
You can skip the oil and incense all together and use the blood of an actual vampire bat for the same exact effect; arguably a stronger effect, but good luck getting your hands on that. I’ve tried.
