Disgaea: Hour of Darkness
There are two hidden switches in the castle. One is behind
the throne, and another is near the skull on the counter of
the Rosenqueen shops. Flip both of them to allow access to
Etna's diary, which is in the middle corner of the
intermediate hallway between the throne room and the shops.
If you visit this area consistently for each chapter, you
will be rewarded with a Testament item in the final chapter.
Get the most out of your turn:
If you are trying to level all of your characters mainly by
using team attacks, etc., move all your characters into
position for a team attack. As long as none of them besides
the initial attacker have not performed any actions, after
the team attack you can move them back to their original
locations and move them again. Repeat this as desired. This
also works if your characters are just out of a healers
range; you can move them, heal them, then move them back
In stage 5, level 3 (Terrible Cold), there is only one
Geopanel that does not have the invincibility attribute.
Combine all the enemies by throwing them into each other,
making one high level enemy. Throw the enemy onto the
Geopanel that is green. Trap him/her on the Geopanel without
invincibility by surrounding him with your characters. Since
all of your characters are on invincible panels you cannot be
defeated, yet you can wear down the high-level enemy who is
trapped on the non-invincible panel. This is a great way to
jump 10 levels at once early in the game.
