SC mid-Chapter 8 spoilers:There are 4 "Orbs" (Power, Mind, Shield, Soul) you can gain as drops from special monsters that appear at the top of each Tetracyclic Tower in Liberl. They only appear in Chapter 8 and are some tough customers, especially since some of your party might not have access to Arts. They each significantly raise one of a character's stats (Power Orb raises STR by +50, for example) and also give a minor boost in SPD and MOV. Never heard of a Gold Orb, though. You sure you read that right?
Ahh I see, yeah maybe it was a
shield orb I saw
