Den of Thieves (Battle #3: Brigands' Den)
This battle is tremendously easy. Now that I have access to actual bows, my archers no longer have to worry as much about positioning --- simply get as high ground as possible and close in, and strike. No longer do I have to worry about accidentally hitting the wrong target (such as another character) and the bows actually do decent damage, as well!
Milleuda is downed easily, excepting that she had a White Mage ally with Hi-Potions, which managed to bring her from critical back up 70 HP twice, which was frustrating. However, the constant barrage of Charge +1 and Charge +2 kind of up a damper in her day.

Goodbye, Milleuda (Battle #4: Lenalian Plateau)
Again, this battle is super easy. Archers advance, Milleuda falls. A Time Mage managed to get off a haste on one of the Black Mages, but it didn't matter in the end. One archer downed by magic isn't enough to stop the arrow onslaught.

Wiegraf, Take 1 (Battle #5: Fovoham Windflats)
I love these assination battles. Delita is an idiot, of course, and runs foreward and throws a rock at the chocobo, and then proceeds to die through a combination of swordskill, pecking, and wave fisting.
I take out the chocobo as I advance up the hill, and then a few charge skills brings Wiegraf down to critical HP with ease; battle over.
