I got stomped by Lady Yunalesca, and decided to go back to the Calm Lands (which I didn't know you could walk back!) to fight monsters and build up my characters.
Here's my question. What's the best method of doing this? Are there certain characters that I should focus on? Is there somewhere specific that I should go to fight ones with the best points?
Also, where the %#$%#$ do I get Lvl 2 and 3 and 4 key spheres? I must have walked right by em . . .
