Disgaea: Hour of Darkness Tips
In Episode 13, The Gargantua Deck level allows you to pick up high level items quickly. As the aim of the level is just to get one character onto the yellow square on the far side of the map, simply stack a couple of characters and throw them to within walking distance. You won't get any HL, but you will get an item or about 5000 XP. You can then sell the items, and, if you lose low level characters, level up a little whilst doing so.
