Jade Cocoon: Story Of The Tamamayu Codes -

Free Mugwort:
Enter Beetle Forest for the first time. Koris is there, waiting to train you. Talk to him, and go to attacking and defending. He will give you a free Mugwort to start with. Disobey his commands while in training. He will make you start over, but you will still have the Mugwort. Repeat this process to get free Mugwort.

Hint: Defeating the Fire Boss (Beetle Forest second time):
Have a water minion that knows Vahlia (powerful water attack) at level 14/15 or higher.

Hint: Capturing a Minion:
When you try to capture a Minion, hold Right and press X. When the gold ball, go around the Minion and hold X.
