Star Ocean: Second Evolution (Part 22) - Fun City Revisit (N.F.I.D.)
Fun City is north of Armlock. Save before entering. When you do, you'll get a long scene, followed by the Sacred Tear and Fallen Hope weapons for Claude and Rena (both weapons drop MP use to 1/2; it's great!) and the Void Matter, which lets you harm the Ten Wise Men. Talk to the man at the left to get a choice to train more, rest for free, or finish up and talk to Narl. Training pits you against fairly easy enemies which give you nice experience (you've seen them all already), with the exception of the Takicodos, which can do some damage and force you to rest after fighting them. When you're satisfied, rest, save nearby, and choose "Go talk to Narl". A battle will ensue.
If one character has Bunny Shoes, have him/her use Provocation and keep running away from Marsilio while everyone else pounds him. Alternatively, you can use a Skanda Compress on a character (or Skanda Ointment on all of them) to have the same effect as the Bunny Shoes. Long-range techs and spells work best. A long fight, but not that difficult. You'll win a Fairy Glass from him. You'll then end up one screen down. Go left to rest if you wish, then save and head out. Try to exit the screen for one more fight, this time with Shigeo. Again, speed is good. I found him much easier than Marsilio. Claude's Ripper Blast works well, as do other multi-hit techs and spells (spells do more damage against him than Marsilio), or regular attacks using Eternal Sphere. Equipping Fire-resistant armor is good as well. Watch out for his Infringement attack, which can hit you wherever you are and have a small chance of stoning you, as well! You'll win a Pyre Tear from him. Now exit Fun City (rest up at the inn if you wish) and head to Armlock. Save before entering.
As soon as you enter Armlock you'll have a scene, followed by a fight with Berle. This one is really tough. When he uses Meta-Guard, nothing will hurt him, so put all your fighters on "Stay away from the enemy!" When it goes down, switch back. Multi-hit techs can keep him from putting it up. His physical strength is very high, so Rena should be on "Recover allies only". If you surround him with fighters you can get quite a bit of damage before he manages to break away, and dizzying attacks like Flame Thrower are great. Spells don't do so much damage, so you may want to consider having a third fighter instead of Celine/Leon. You'll win a Merlin Drink from him when you're done. When you exit Armlock, another short scene will play out. You're now ready to enter the last dungeon
