Other Ecology A is one of the many rare items you can get in Scarlet Nexus that only drops from a few enemies in the game. So, if you want to get Other Ecology A, you will need to find and kill the following enemies in the game.
- Fuel Pool
- Buddy Rummy
- Scummy Pendu
You can find most of these others in the first area, Kikuchiba, in all areas such as the sub-level, marketplace, and construction level. For others like the buddy rummy, you can also search in places like Mizuhagawa NCD Dist and the construction site.
You can also check where you can find any of these monsters via the enemies tab in the library. However, to make the most of your farming, we highly recommend using brain crush as it will force enemies to drop rare items upon death. That said to use brain crush, you will need to do either rush follow attacks or psychokinesis follow-up attacks.
Using one of these attack combos will help lower an enemy's crush bar, allowing you to use brain crush to kill them. So, If you want to do a rush follow up attack, you will need to first need to do a psychokinesis attack (RT or R2) and then hit X or square for a follow-up attack.
For psychokinesis follow-up attacks, you will need to first land an attack with either of the main attack moves (X/Y or square/triangle) and then follow up with a psychokinesis attack (RT or R2).
