This could work as a hint for those unaware of this thing.
I usually tend to work up my characters to some insane stats and stuff, while still having Minh in the party, and I train right north of Phin, where you encounter Wizards and Wz. Ogres.
I could safely say that this is the best early game training place I've ever heard of.
Not only do you gain some incredibly high level magics for free (Berserk and Stone, anyone?) but you gain WEAPONS as well!
A few seconds ago I defeated a single Wizard, and the screen went this weird as it usually does when loading the Treasure Screen.
I thought it was another great magic I could sell for big money, but it turned out to be a Magic Cane.
I went like "damn it" and guessed I might as well use it - I got really surprised at the incredible strength increase for Maria.
She had the Cane, on 5 Attack Power, and changing to the Magic Cane increased those points to 41!
This place is incredible!
