The fastest way to level your characters is by redoing easy side quests. By far the easiest side quests are the ones where you spend 2k/4k/8k/16k and get the same amount of experience back. Some characters, like dorn, don't have these. The necromancer is restricted on how quickly he can do his side quest and his guy is furthest out of the way, making him the hardest character to level up in this way. The cleric falls into the middle difficulty, because the church isn't in the same building as the fastest two characters. The monk and dwarf are the fastest two characters to level up in this manor. When in a multiplayer game, both characters gain the experience for each quest. So it is more like a 4k/8k/16k/32k quest done in two steps.

What does this mean for characters like dorn? Now he too can tag along for the ride and gain this cheap experience. You just have to use two controllers and two save spots on your memory card and you can't do the two times experience per load trick.

That is quite a chunk of change though.

You open the cheat menu and level warp from boss to boss. You can do the side quests for characters you don't have this way as well.

Though you can corrupt your save file with this method too.

The cheat menu can be accessed with: Press and hold L1,R1,triangle,square,circle,x and start
