Wearing a Prinny cap is one way to power up Renya and the angels that accompany him in The God and Fate Revolution Paradox. Equipping divine treasures changes what attacks Renya has.
While you can get to level 9,999 in Disgaea, The God and Fate Revolution Paradox resets Renya back to level 1 when you leave a dungeon. Just like Z.H.P. Unlosing Ranger vs. Darkdeath Evilman, players can customize Renya by building Holy Circuits. You can place chips around sacred objects that boost attack, defense, hit, and speed parameters. Complete a whole circuit and you can even more of a bonus.
You can also customize angels and make a "holy shield" by creating a circuit just with defense
Or make a spy angel by boosting hit and speed. This gives your angel a high chance to deal critical attacks.
The God and Fate Revolution Paradox has traps scattered around dungeons like a bear trap that stops Renya from moving. Another angel can lift Renya out of it so he can escape.
That minefield might be useful since Renya can throw enemies into traps. Other dungeon gimmicks are helpful like the jet which lets Renya fly past enemies.
The God and Fate Revolution Paradox comes out on January 24, 2013.
