Trial: Defeat a set number of experience-yielding monsters under the prescribed weather conditions, or on the corresponding day of the week.
Objective: 300 Plantoids.
Equipment: Target item must be equipped.
Good Location:Another good place is Bhaflau Thickets in the F/G - 6/7 area. Kill Olden Treants and Treant Saplings. Bhaflau's Wind weather is a bit more reliable than Grauberg, since Grauberg gets Thunderstorms a lot also.
