what do you mean "getting all checkers pieces" from Egbert? do u just recruit everyone and that's that, or do you have to win the hard mode many times---?It's Defense/Technique and is obtained after getting all checkers pieces from Egbert. That's pieces for the 108 stars and Lymsleia (Hard Checkers only), Ferid (Hard Entrapment only), and Arshtat (Hard Conqueror only).
does the Treasure Hunt (on a fighting character) skill work when the character is in Entourage? other ones do even though they don't pop out on the menu like regular Support characters
