This is why I love the Disgaea series (even when you probably can't win, you can)
Story time!
Ok, so I've been playing Disgaea 2 for the past week or so (working on the next Cheat Sheet ;) ) and I got to the battle with Shura and Serion. I remember one of the NPCs mentioning their evilities but somehow completely forgot about it when I got to the battle. Heck, I even checked their evilities at the start of the battle but still somehow forgot.
Making my way through the battle and lose my Magician early on in the fight. No biggie, he always dies. I finally get to Shura and Serion and well, you probably realize the problem. Losing my only spell caster will be a problem for taking down Shura.
Me thinking I'm big brain, I use an element based attack...0 damage. Suddenly, I'm in a bind. Only spells do damage and I'm fresh out of those. I have Adell, Pleinair, Rozalin, Hanako, and the Cleric they give you at the beginning of the game.
I come up with a brilliant idea...Geo damage. I toss Shura onto a geo panel and pop one of the colors. 40% of their HP is depleted. AIGHT BET. I do it for the other set. 42% is depleted...and now I'm fresh outta geo symbols to use.
I'm sitting there cursing that my Thief was lost b/c I could at least Poison this last enemy and then I remember...my Clergy is a Bow user, and has Poison Arrow.
I sit there going "welp, only one shot I get this...." and I not only hit but also trigger the Poison. I win the battle.
I literally ran across my home celebrating that I pulled off that win.
This is why I love the Disgaea series...b/c I can pull off shenaningans like this.
I then did the Dark World stage for it afterwards and again won via Thief shenaningas (seriously, the ailments are INSANELY powerful!).
