Tales of Symphonia Cheats

After receiving special items from the Summon Spirits, you can change your weapon's element in order to deal more damage to some enemies. For example, using Water against a Fire-type enemy. Incidentally, some of these allow special techniques once conditions are met. Refer to the "Special abilities" hint for details.

When it comes time to do the Earth Temple in Tales of Symphonia if
you get the warp door where there is always a dragon, fight the
dragon for as long as you want.  Every time you defeat him you'll
get 10,000 gold and 800-1000 exp points.  After you get to higher
levels the gold will be the same but you exp collectings will drop
to around 600-800.
 

To fight Aviation, collect the nine Darkness Weapons and go to the Darkness Temple.

Not sure if anybody knows this but here goes.

After you watch the very last scene in mithos' castle go back and talk to altessa and dirk they will both start customizing so you can get more faerie rings, rabbits foots etc.

hope this helps.
