Few questions

[Daybringer]

I have a few questions here:

1) How do I change my outfit/ where do I go to change my outfit?

2) I haven't tried looking yet, but is there a strategy guide for it, if so where?

3) How do I use a Barta or any other spell amplifier?

4) Got any tips for beating De Rol Le and about what levels should everyone be if 4 people fight it and are competant?

any answeres would be greatly appreciated.
