Infinite Experience (without using Cheat Menu)
Similar to the Cheat ''Infinite Gold or Duplicate Items''
Get to a save point right before a boss that gives A LOT of experience. Example: Beholder, Drow Elf Sorceress, Dragon, Onyx Golem. Save the game.
Defeat the boss, then go back and save the game under a new file. Load the original file (before you fought the boss). Import the character from the new file (after you fought the boss). Go fight the boss again for more experience.
Repeat till you reach whatever level you wish. The massive experience you get should make it easy.
Level 20 Character and 75000 gold
When in play mode, press L1, R2, Triangle, Left D-Pad, R3 and start simultaneously to instantly make your character 20th level, with 75000 gold, 1000 Health and 1000 Mana, and a minimum of 1 in every feat, including OTHER character specific feats.
However, downside is that your character does NOT gain any further experience points while playing, and is stuck at 20th level, with low level feats. The normal character max is 40th level.
