Adell and Rozalin
Use the following steps to get Adell and Rozalin from the second Disgaea on your team. First, successfully complete the Cave Of Ordeals. Once this is done, the Demon Hall Mirror will be available. Do this level four or five times, and you will have to fight Adell at level 2,000; then Adell at level 2,000 and Rozalin at level 2,500 at the same time. When they are defeated, they will join your party. Demon Hall Mirror will also become a good leveling up location.
After losing to the mid-Boss and starting a new game, speak to Plenair, and go through the Dark Assembly Tutorial. Speak to her again. When your options appear, there will be a blank space above the “Exit” option. Press A on it, and Plenair will say something similar to “They’ve found me…” and automatically join your party at level 1. She has incredible speed, uses guns as her main weapon, and already has the Nether 35 and an Imperial Seal equipped. Her first special attack is Usagi Drop, which is just about the same as Prinny Barrage but with bunnies.
Defeating Item Gods
Once you go into the stage, look at the bonuses for invincibility geo spots. Use your characters to steal all those spots. Then, try to find an area to pin the Item God in, and just whittle his health down. You can use this method to kill Item God 2 in the Aracadia. Depending on your team’s level, you could be a long fight, but you cannot lose.
