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 doesnt follow you back up the path because the game engine doesnt 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 doesnt affect your current characters save file and whatever you, dont 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 execpt 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 charater 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 Corageous, or 19 on Adventurous, with plenty of skill points to distribute.
