Bestiary Observations

Location
* The Etherian will appear only after you have defeated all the other enemies in the Northsward area of the Cerobi Steppe. Etherian can be used to farm High Arcana relatively easily as you can leave the area and return and the Etherian will respawn again. The odds of it dropping a High Arcana is still small though so it may take quite a while.
