Final Fantasy 12

Barheim Passage

Use the Save Crystal in the corner and save your game. Examine the Timeworn Device in the centre of the room, then descend the stairs near the crystal and speak with the creature below to get a Tube Fuse. Return to the previous level and check the room at the far east to find three chests, each containing a fair bit of Gil.

Use the Tube Fuse on the power relay in the middle to activate the lights. Now pres the switch on the wall beside Burrogh while will deplete the charge down to 70%. He explains that you need to maintain a good level of charge in order to actually make it through this area.

Take the southern exit and prepare for another quick tutorial. Your primary goal should be to eliminate the Battery Mimics as soon as possible so that not only do you stop them from draining charge, you actually replenish some that was already lost.

Assuming you have the Libra effect equipped you can see that the Battery Mimics have a substantial weakness to ice magic. For this reason one of the first things you will want to do whenever you see one is target it with Blizzard magic.

Take down this first Mimic and continue around the path. As you progress down the stairs, you may wish to ignore the small Mimics in favour of going after the Battery Mimic at the bottom first. Defeat the enemies and proceed east.

There are at least two Battery Mimics in this next room, and not necessarily close together. Quickly eliminate the first and then ignore all other enemies as you run south to locate the second. Afterwards you are more than welcome to run back and look for any chests you may have passed.

Ignore the first fork leading southwest (after disposing of the Battery Mimic) and head straight south to another fork. The more eastern fork leads to another battery Mimic and potential treasure chest. The other fork will take you a little further south. When the opportunity presents itself, take the other path back north to find an with the map to this area inside.

A pointless room with a couple more Battery Mimics awaits you to the west, you are under no obligation to clear it. Your real destination lies to the south. When you enter this area, quickly dispose of the first Battery Mimic you see. The second hides in a room at the end of the east hall, though you will have to circumnavigate a couple of Flan enemies in order to catch him quickly.

From this room you can climb the stairs and take sort of a northern exit off to the side. This whole room is filled with Flans and battery Mimics. Your goal is to make your way toward the far northwest corner where a gate switch can be found at the top of the stairs. It require 30% charge to activate. When you're ready to proceed further, what you need to do is return to Special Op Sector 3 (the previous area) and head south.

Save your game and continue south. Keep an eye out for Mimics disguised as chests. You will also watch to keep hunting down Battery Mimics whenever possible. Use the slowly depleting charge to determine whether one is nearby, and the red icons on your minimap to find them.

There are quite a few Battery Mimics in the area south of this one, three to me exact. The best course of action to take is to begin by targeting both that start near the entrance with a Blizzard spell and proceeding to wipe them out for there. The third is located in a rather inconvenient place, you must run south to the bottom of the ramp and then northeast to the top where the final one is found.

Make sure to go back down and open all of the many chests found in this area, including the possibilities of some equipment and new Gambits. Travel up the slope to the northeast corner where you will find the exit. Save your game and prepare for another boss battle.
