Disgaea 4 A Promise Unforgotten: X-Dimension Guide Chapter 10 Pt.1
Last chapter of this guide, kinda sad to put it down, well until the King Krichevyskoy, Marona and Ash DLC comes out. So let's do it.
Stage 1: This level is a bit of a pain. You're supposed to let the red symbol encroach to create an area of green. You can kill them off before the Geo Block blows up and it's a good idea to stand on the Geo Block to prevent someone from destroying it with an offhand attack.
Stage 2: I will admit, it took me a couple of tries to realize I could actually hit the Geo Tower with the Ghost on top to bring it down. Kill the Succubi and work your way up the "stairs" to the Ghost. Have some characters hit the Geo Blocks under the Ghost so he could be bought within range of your character's magic attacks.
Stage 3: Survive and lift your way to the Invincibility Block on a yellow panel. This level gave me some trouble due to the coloring and I couldn't really tell where my characters movement range ended so it's possible I could of finished this level sooner. Once you move the Geo Block off the yellow panel, go to town on the mages and witches.
