Ordeal 4

Ordeal 4 is the fourth stage in the Disgaea 2: Cursed Memories Cave of Ordeals. It is one of the best leveling maps. A fight with 8 Mad Jesters which are all inside the +100% Experience Geo Panels and +100% Mana Geo Panels. They have no equipment and their base level is 250. 3x3 grid attacks like Winged Slayer and Big Bang are useful in this map but some of the enemies can be 50% resistant to fire element. Another good thing in this map is to use 2 characters with Dimension Slash. You can also pass the Strongest Enemies bill. Their highest level is 1290.
