Dunnow...I use different parties so I change often.

When I'm in my Mage mood, I usually have these:

Faroush, Lyon, Levi, Zerase, Jean, Eresh

Other parties:

Faroush, Lyon, Richard, Cathari, Zerase, Levi

Faroush, Lyon, Miakis, Georg, Zerase, Richard

Standard in my entourage:

Egbert >> Potch Finder is one hell of an ability!
Takamuku >> Escape Route FTW!
Zweig/Lorelai >> Treasure Hunt <333 next to that they do well as Party members in battles when I need to switch

I'm very fond of Richard and his Swallow Rune <3
