Another thing. What happens when you get 20 gems for each og the fairies? I got 10 and some already.
At 10 gems, you can upgrade the fairies to level 1 at the uncharted fairy island.
At 20 gems you can upgrade them to level 2.
Level 1:
Power Fairy - Do extra damage, probably 1.5x.
Wisdom Fairy - Take 1/2 damage.
Courage Fairy - When you attack you also shoot a thin beam wave.
Level 2:
Power Fairy - Do extra damage, probably 2x.
Wisdom Fairy - Take 1/4 damage.
Courage Fairy - When you attack you also shoot a wide beam wave.
I think the fairy island was in the southwestern area to the southwest, but I can't remember for sure.
