Strongest sword
     If  you  get the rusted great sword from the stone, DONT throw it
away.  If you up-grade it a lot, it will become the strongest sword in
the game.

Training School
     To  unlock  the  training  school,  you  have to unlock the Lvl 2
missions from the town sage and complete the mission 'The Great Jungle
Kut-Ku'.  This  will unlock a training school for you to fight against
the  kut-ku with limited weapons,armour and items. When you beat other
powerful monsters they are also trainable against here.

Beat the Yian Garuga 'Urgent Quest' easily
     First have nothing in your inventory except for a spiderweb. Then
start  the  quest. Run to area 7 on the map and talk to the man there,
he will take your spiderweb and give you a special mushroom. After you
recieve  the  mushroom,  wait until the time run's out. When time runs
out, the game thinks you beat the quest.
