how can i get freya's ultimate weapon??? i need to know! i know you have to use a dead pepper or something, but where??

It's in Memoria. In the room north of the first one, where you speak to Garland. It is in the eastern part of this room.

no that's here second best weapon, her best is on the forgotten continent, north of ouilvert you'll find a small forest surrounded by mountains and you must use a dead pepper in the mountain crack
