How can i farm cores from low level monsters?

Its different. When i’m visiting the low level areas, i wont even get a fight. Only some minor exp, when i touch the roaming monsters.

You have an item that automatically kills those low level monsters, if you toggle that off, you can battle them as normal.
I believe it’s under miscellaneous items or something?
