To get your stats very high very fast its simple:
Step 1: Make a character and DO NOT USE THE POINTS WHEN YOU LVL!! Save EVERY point from lvling.
Step 2: Once your character has accumulated around 30 points or more (I usually wait until I have lvled the character to lvl 21 which gives them about 60 points to spend in stats)beat the very first stage and collect the Stone from Rallos Zek.
Step 3: Go back to Firona Vie and the back to the portal. Select the special stage from stage 1 (the 4 horsemen) and enter it.
Step 4: Once you are in, allot your points into the stats you want, dont worry about your skill points right now, just put the Str, Int, Dex, or Stam points in you want, use the all.
Step 5: This sounds stupid, but now.... DIE, just let the horseman kick yer ever-lovin arse.
Step 6: Press TRY AGAIN, DO NOT EXIT OR THIS WILL NOT WORK!
Step 7: Once you have restarted, you will have all your points back and will be able to allot them once again and the points you have already alloted will still be there!
Step 8: Repeat as many times as you wish. With this cheat/game glitch you can have a lvl 21 with 2000 Str, Int, Dex, and Stam in about an hour or so.
To get another character lvls very fast and easily:
I did this on "CHAMPION" difficulty.
Lvl 45 Warrior with Str, Stam, and Dex all over 1800. Go to the last boss (Cazic-Thule or Mith Marr) on 2 player mode with my Lvl 45 Warrior and a Lvl 1 Character I had made (Ranger). Used my Warrior to destroy Cazic-Thule and everytime I did my Warrior and the Ranger gained 1 Lvl. In about 2 or 3 hours I had a Lvl 41 Ranger and a Lvl 61 Warrior. Not to mention, I got a full set of 245 defense armor and LOADS of other goodies. Then, once my Ranger was high enough Lvl to use it, I simply duplicated the armor so now I have 2 sets of it and 2 pretty damn good characters. With my Warriors current stats he is hitting for about 12,000 damage and critting for hella more.
