Most of the monsters in this sequence aren't that hard, although the Baron Warriors and General seem to be a pain in the ass for some.
Here's two common behaviors noticable in this battle:
1) The Baron Soldiers primarily attack when told to. They are naturally slow as molasses by themselves.
2) The Baron General has no balls.
The character that has the most impact is Edward, but not for any obvious reason. The Lamia Harp is not effective at all, even though Charm status is pretty powerful.. here are two simple reasons why it is useless:
1) The Charm script for the General is the exact same as his standard battle script.
2) The Baron Warriors are resistant to Charm (Twist Headband anyone?)
If you were smart enough to keep the Dreamer Harp, this battle becomes easy as pie.
There are two reasons why this is successful:
1) They aren't bosses, therefore no auto-status immunities from physical attacks that induce statuses.
2) All of them are not resistant to Sleep.
Once you realize this, these warriors become very harmless and you can easily obtain free EXP from the General.
