oh by the way...about that Javlin 2 your talking about....you can snab one in the deep dungeon heres a quick tutorial:

(SPOILER)Ok real simple. Equip all your characters with the catch ability before going into a random battle in the deep dundeon. It dose not matter which fight you do. As long as there is an enemy Ninja present you have a chance to get one. When the battle starts the enemy ninjas will throw random items one of them being the Javlin. so..the more ninjas present the better the chance of getting the Javlin.

oh and if you thought the Chaos blade was powerfull...I do believe the Javlin 2 is slightly better......
