Reward DQ9 SeedOfDefence.pngSeed of defence; DQ9 ToalOil.pngToad oil for repeat
Detail A farmer named George from Zere has asked you to chase away the betterflies that keep attacking his crops.
Hint for solution Have someone at a high enough level to make 10 betterflies flee from you in battle. Level 25 is sufficient. Betterflies can be found in the farmland area near Zere. The betterflies will eventually flee on their own if the player simply defends each turn.
Repeatable Yes.
