Red = Strong against you
Green = Hasn't figured out you're there yet
Blue = Weak against you

At the beginning of the game before you do anything go to the shop in
Ourt Village and go to the counter and talk to the man and he will give
you a red marble!!!YAHH!!!

At the end of the game when you fight Lord Bellias and Octum, be sure to be at least a lvl 43 for everyone in your team (what would be even better is if you're lvl 44).

Also if your lvl 43 get your exp. down lower than 300 and when you fight Lord Bellias he'll give you enough exp. to lvl up to lvl 44.

PEACE OUT!!!

This might be a drag but, at the beginning fight the slugs until your lvl 3 and later on if you keep leveling up.The monsters attitude become usually blue and you wont have a hard time walking around.
