Disgaea PC, part 26 - War of the Netherworld, Part 1.5
OK, now this is one annoying stage. Invincibility on the high ground, but also 20% Ally Damage each turn (that goes through Invincibility), and if you want to avoid that and use the low ground you run into buffed enemies. I really don't know what the best solution here is. It's definitely not to destroy a red Symbol on the green Geo Panels to make the entire map invincible and basically unwinnable like I did in a failed run. I settled on making the green panels a total nightmare and trying to lure enemies onto the high ground for a fair fight. Good thing the AI doesn't evaluate Geo Panels for the purpose of strategising moves.
