The Barheim Passage

Run down and go into the right room to get some gil. A Save Crystal is in
the other corner. Now head to the tower and examine the switch, Balthier
tells you to get an energy source to active it. Talk to the Bangaa at the
bottom to get a Fuse Tube, now you can active the switch. Press the switch
at the tower and another near the Bangaa to open the gate. Before leaving,
buy the Blizzard magic from the Bangaa merchant.

Next area, defeat the zombie and kill the Battery Mimic to keep the battery
energy from depleting. You need to kill all Battery Mimics in the following
sections to gain battery energy. In the Great Eastern Passage, turn back to
the broken railway on the right to find the urn, hit it for the map of this
place.Go into the right station to find two more Battery Mimics, some Flans
are here too, use the Fire spell against them if you want to kill them faster.

After that, head to South, then go West from the next section. There's a switch
in the North-West end, and you must press it to open the Southern gate, back to
South route. Find the Save Crystal after the scene, then advance to the next
area. Another Save Crystal in the South-East railway, after this is the boss
fight, so make sure you save you game here, learn the Blizzard magic before
the fight.

Some small mimics join with the boss, killing them is just a waste of
your time, just focus on attacking the boss, now Basch has slightly
higher offensive power, so don't let him die during the fight. Thunder
spell will heal the boss, but Bizzard spell deals the most damage, that's
why you should buy it from the Bangaa at the beginning of this area.

The Nalbina Dungeons

Currently you have lost all your inventory, but will get them back soon. Search
around this place for some items before leaving, use the Save Crystal near the
exit. Afterwards, defeat three Seeq enemies by using Vaan and Balthier. Fran
rejoins party after this battle.

Next area, you will get your items back as well as the map before the Save
Crystal. Don't open the other treasure chests here, like the one in front of
the Dalan's Place and the Elixir in the palace, it has some connections with
'Strongest Halberd' weapon which you can obtain later. Read the "11. Weapons"
section for more details about this weapon, again, it's call Zodiac Spear as
well. Next place, defeat the imperial militaries when necessory. An event
happens when you come to the central North area. The Judge has opened the
door, get in there to meet with Basch, and he will join as guest character.
