The Dark Force is the hardest boss in the game. It can inflict massive damage on everyone in your party in a single hit, and has the ability known as "Evil". This nasty little power turns one of your party members and can have them steal items from other party members and use them like Star Mists. The "Evil" hypnosis can cause members to become unresponsive, try to flee in vain, refuse to attack, heal or use techniques.

The Dark Force has roughly 2,560 hit points, the most in the game and the highest damage rating of 320. With the aforementioned "Evil" power The Dark Force is truly a pain to defeat. You should not even attempt this before having at least the main members of your party (Rolf, Rudo) to level 35. My party was Rudo and Rolf at 30, Anna and Amy at 29. I lost Amy, used Nafoi and only one Star mist the whole battle. I got lucky also since the Dark Force kept using "Evil" techniques and only attacked me 5 times total. Your mileage and personnel will vary. Save and reload trying the tips below. You could get lucky and defeat the Dark Force at a lower level than me. See the bottom edit for a way to quickly level in the dungeon of Noah.

From the get go you should have the nine Nei items found on Dezo since they are required to get to The Dark Force/Mother Brain. Have Nei Shot on Rudo, Nei Slasher on Anna, Nei Cape on either Anna or Amy (Amy in my case), Nei Met on Rolf, Nei Armor on Rudo, Nei Crown on Amy, Nei Emel on Anna, and finally Nei Shield which went unused. The Nei Sword is given to you by Lutz in the Esper Mansion after obtaining the eight others. These are by far the strongest items in the game, and getting them will help level you for The Dark Force battle. Everything else up to this point should be a Laconia weapon or armor and Hirza/Garda/Shune boots all which can be bought (expensive!) on Dezo.

This guide is written assuming your at level 35. This level is important because you get the spell Megid which does an extreme amount of damage to everything. Megid is not required, you can beat the Dark Force without it, but it makes it a lot easier. Since the game has a save function, use a walk, save, walk, save (or keep hitting the investigate button X as you walk) to make sure your at full HP and TP and start the battle. Immediately have Rolf throw out Megid on the first round. Megid takes 1/2 HP from each party member except Rolf, and deals that number of HP damage. At the level your at, this is a massive amount of damage, more than any single attack. It also costs 55TP which limits the amount of usage. Also in the first round have Amy use the Snow Crown (or cast Deban) which will help lower the damage received from the Dark Force. Immediately have someone use a Star Mist to heal everyone while having Amy use her Sashu technique which increases the defense of the party. For the remainder of the battle have each member attack as usual (or heal other members), and constantly use Rolf's Nafoi technique since it does more damage than his sword attack (125-150HP). Occasionally the Dark Force will use an electricity beam which damages all party members, this should be countered with Star Mist or a Gisar technique. The electricity beam is especially crippling to all members of the party.

The battle is a long slog and will ultimately depend on who can outlast the other. Make sure if party members are falling below 1/2 health to heal them quickly since the electricity beam can quickly kill off the last 1/2 of remaining life. Once defeated the achievement will pop.

Maps to all the dungeons can be found on, as well as a more detailed walkthrough. Hope this helps!

Edit: To quickly level your characters after getting all Nei items and having Lutz transport you to the Noah dungeon, just walk around start a battle. Walk around and fight battles, heal only using techniques. After using all TP points use the Nei Sword to transport back to Lutz where he will heal you, go back to Noah, repeat. You should be able to get 10-20,000 total party exp per battle allowing you to level quicker. You can go up 4-5 levels in a few hours using this technique.

Mother Brain and Dark Force can easily be beaten at a level far below what the other guide recommended. That's assuming you are willing to manipulate save states. I beat both bosses with Rolfe at level 28 and Rudo, Amy and Anna at level 27. I also didn't use any healing items or techniques besides Trimates.

Make sure you save into a different save file before attempting either boss using this method in case something goes wrong.

Dark Force:

What the other guide fails to explain is that in battle, you can press the 'B' button to stop your characters from attacking and let you strategise. Use this every turn so you can heal when needed.

Save the game at the start of each turn. Dark Force will randomly either attack your whole party for huge damage or turn one of your members evil, which will stop them from attacking. First cast Deban by using the Snow Crown item. This will half all the damage you take from attacks. If you fail to get Deban casted, reload the save state and try again.

Rolfe's Nei Sword will randomly heal a cursed party member form being evil at the end of each turn. You can manipulate save states until a party member is healed if you really want them active.

Both Anna and Amy were dead half way through the fight but it didn't matter. Rudo and Rolfe were more than enough the finish off the fight. Keep saving at the start of each turn and if you aren't happy with the results of what happens next (like either party member missing an attack or something), reload the save state and keep trying.

I beat Dark Force on my first try. No heavy grinding needed.
