Once you get to the Cloud Giant King in the Tower of Clouds attack him like you would any other time you have fought him, but stop just when he has a sliver of life left.

Once you have his life down to whatever you consider almost dead, run back to the save point that you found just before you got to the Cloud Giant King. It is very important that you make sure he doesn't follow you back up the path because the game engine doesn't let you save if it thinks that you are still fighting anything and if that happens the cheat is impossible to complete. Once you get back to the save point use a gate scroll. Go to the shop keeper and buy about 20 or 30 exploding potions and gate scroll back. Once you are back drop the potions on the ground. After you have dropped all of your explosion potions save your game, but make sure you save it as a new file so that it doesn't affect your current characters save file and whatever you, don't ever save over this file.

Next, create the character you want to get to a higher level. It is very important that you start from the character creation screen and not to use a character you have already been playing with because it will ONLY work with a lvl 1 ( 0 exp gained) character. Once you have your new character made, as soon as you gain control of your avatar go directly to the save point and be sure not to kill any orcs. Save your new level 1 character over any save file except for the file that is your tower of clouds save.

After you have successfully saved your new character re-load the 'Tower of Clouds' save file. Once back in that game load in your new level 1 character into the 'Tower of Clouds' save file, replacing your higher level character.

With your level 1 character go around and pick up all (or as many as you can) of the explosion potions that you had previously dropped and run down towards the Cloud Giant King. Kill the Cloud Giant King with the potions and you will instantly become level 50 on Champion difficulty, 39 on Courageous, or 19 on Adventurous, with plenty of skill points to distribute.

Raise your attributes to 100 during character creation  -  From the main menu, choose "Start New Game," "Normal Game," and "Two Players" (you must have two controllers plugged in for this option to be available). Once in the character creation interface, create Player 1's character as normal, then continue on to Player 2. Player 2 advances to the character attribute configuration screen, where they have 20 points to assign. Without assigning any of the points, have Player 2 press the Circle button until they are asked if they want to back up to Player 1's character creation screens (they will have had to press Circle three times from the attribute configuration screen to get to this prompt). Press X on Player 2's controller to confirm. You are returned to Player 1's name entry screen. Player 1 presses Circle once to back up to their attribute configuration screen, where they now have 20 more points to assign to their attributes, in addition to the 20 they gave themselves the first time through.

You can repeat the process of going back and forth between Player 1 and Player 2's attribute configuration screens, gaining an additional 20 points for Player 1 each time. Each of the four attributes can go up to 100. However, you must be careful not to use the glitch so many times that you have over 400 points total, because you will not be able to assign the additional points and the game will not let you continue, saying that you have to assign all of your points.

You can use the process outlined above to raise the stats for up to three characters at a time. Once you have control of your characters in the game proper, you can delete the superfluous non-maxed character from the party by using the Select button menu.

Secrets  -  Death to Elves  -  There is a glitch in Act 1. Any npc elf running around, not stationary, can be killed. They give roughly 140-160exp each. You can kill them by selecting the erudite wizard select the spell Shock of Fire and aim it by an elf, make sure it hits something so it will explode next to them. It takes a little time, but shortly they will perish giving exp, and items and a little gold.

Quick attacks  -  If you have a one handed weapon equipped press the block button and attack button simultaneously to do a very quick strike, use this on a close enemy and you can see the damage rank up.
