Disgaea: Hour of Darkness/Episode XI: Hero's Will, Overlord's Way

11-1: Ghostly Whisper
The enemies here are lined up nicely for you to slaughter with your AOE attacks. They should not be a problem. Better still, they are standing on Exp+100% Geo Panels.

11-2: Rising Fear
The trees in this map will obscure your view of the whole battlefield. Before you get started, take a look around and keep track of the enemies. Allowing the enemies to sneak up on you through the trees is a good way to lose this battle. The swordsman can be tough, but stealing his weapon reduces his power significantly.

11-3: Crawling Terror
Throw as many characters as you can toward the geo symbols. Destroy them and then destroy your enemies.
 * V.1

Take Laharl and one mage out and slowly edge your way foward taking breaks in recovery squeares when neccesary destroy it in one turn
 * V.2

11-4: Hero's Tomb
The stage is affected by Enemy Boost x6. Luckily, there is an enemy in a straight line from the geo symbols who you can throw to destroy them quickly.
