2. Ambergris
This right here is a secretion that can be found inside the stomach of a sperm whale. The funny thing about this is that ambergris has a very foul smell. You can’t even go near it without feeling like throwing up. But once is dries out, the smell goes away and that’s when you can use its main characteristics, which is fixative. A small touch of this substance will make your perfume last for days. It’s a very rare item, though, and can be randomly found on the water bodies, floating directionlessly.
