(This tip is for hard mode players only) In the beginning of Tales of Symphonia when you have to go to the temple with Colette so she can get the Cruxis Crystal and start her journey, before heading there, you should train to lv.7 or at least lv.5 because the the big desian guy is hard to beat. So train to about that lv and he shouldn't be that hard.

In the snow village, (I forget the name) when the other characters ask you to come outside and talk with them 'say no' to all of them and then you will automatically go outside after you say "no" and you will see Kratos there. Lloyd and Kratos will talk and Kratos will join you, but then you wont get Zelos. So you have to choose either have Zelos or Kratos before this point.

If you beat swordancer twice, the third one is in the first forest where Lloyds dwarf father lives (and the human ranch is), if you beat him you get Lloyds best weapon (with the best slash). and there is another best weapon (with the best thrust) if you beat the arena with Lloyd alone (hardest mode on the arena battle). But actually Lloyds best weapon is the material blades (which you get automatically get in the game) because he can do falcon crest (his best attack) when your really low on HP go up to the enemy and press A,X,Y (together) to do falcon crest but after falcon crest Lloyds HP goes to 1 so heal him right away. Falcon crest is only useable with the material blades.
