Elder Scrolls, The: Morrowind

Use the following trick to boost all your weapon stats, with the exception of Hand-to-Hand. Note: The boost is the same as previous methods mentioned; the only exception is that you are activating all of the bound spells for each weapon at one time, then pressing the appropriate trigger buttons and holding them throughout. First, acquire all bound "weapon" spells that cover the weapon stats. Make sure you have a spell that raises long blade, short blade, blunt weapon, etc. (one of each bound-type in your magic list). Depending on how much magicka you have, you may have to enable the "Change magicka level" code to ensure your magicka continues to rise as you cast the spells. Cast all of the bound "weapon" spells one after another. Once all of them are active, hold X + L and watch the weapons switch out rapidly. As they switch, the stats associated with each type of weapon will rise tremendously. You can do this as many times as desired until the spell expires. To continue boosting your stats, simply re-do the spells and hold the appropriate buttons your controller.

To raise all stats, Strength, Endurance, and Luck, all you need is Wraith Guard and Sunder. Equip any weapon, and make sure you have the Wraith Guard on. Hold X + L to switch between the Sunder and the other weapon. This will raise the stats of Strength, Endurance, and Luck by at least 90 points at a time. This also works with Keening, but it raises Speed, Agility, Health, and Willpower.

To get superhuman abilities (Strength, Speed, Agility, Endurance, Luck, Magika), you must have a Bound Mace or Bound Dagger spell and the weapons "Keening" and/or "Sunder" that you get towards the end of the game. Cast Bound Mace/Dagger and hold X + L to scroll through weapons for a few seconds. Your skills will jump several hundred points, and you can slay an entire town. The Speed increase is the most impressive, although it can be slightly difficult to handle. This trick makes you practically invincible with stats between 200 to 300 and Health, Magika and Fatigue between 500 to 1000.

There is a constant effect glitch for items that fortify your stats and skills. Basically, if you could enchant any old weapon with a fortify stat spell, you can raise that stat. All you need to do is get a weapon enchanted constant effect. Once that is done, hold X + L + R and it will bring that stat up. For 2,280 gp (on good terms with Enchanter), you can get a sword made that raises strength by 1 point. It does not matter how many points you put in -- it will jump quickly enough. Hold X + L + R and check every once in awhile to see how far up it has gotten. Note: Some other effects may be able to be used in the same way. For example, enchant a weapon with Feather and bring your weight down to 0. If you want to bring every stat up at the same time, enchant a weapon each fortifing a different stat 1 point each. Constant effect, then hold X + L or X + R. This will cycle through the weapons, giving you point gains in each of them.

Another way of boosting your main stats is to create a spell with Soul-trap and a spell that will boost that stat. Start with Soul Trap on self and Intelligence. By doing this you can get more Magicka and its easier to cast the spells. After a few casts, switch to something else. You can boost Health, Fatigue, Strength, Magicka, Intelligence, Willpower, and Luck. If you do not have a spell that enhances your stats, then go back to the merchant in the first village and buy Jack Of All Trades.

Enable the "Change health level" code near water. Hold A and press the B. You now cannot get hurt or drown. Use a rubber band on your controller so that it moves forward automatically. Go to some water and swim. The fish creatures will attack,and increase your light, medium, or heavy armor skill. Check every ten minutes to make sure you have not run out of water. After two hours, your armor skills should be quite high, as well as the skills for swimming and running. Do not return to the menu or you will lose your progress. This trick also works when done against a wall with the "Change fatigue level" code.

Press B during game play to display the options. Press L or R to cycle to the statistics screen. Highlight the fatigue bar, press Black(2), White(2), Black, then hold A to set a new fatigue level. Press B to exit. When your fatigue changes, it will automatically go back up. Note: Only one code can be activated at one time.

Press B during game play to display the options. Press L or R to cycle to the statistics screen. Highlight the health bar, press Black, White, Black(3), then hold A to set a new health level. Press B to exit. When you get hit, your health will automatically go back up. Note: Only one code can be activated at one time.

Alternately, press B during game play to display the options. Press L or R to cycle through the menus to the statistics screen. Highlight your character's health and press Black, White, Black, A, Black, A, Black then hold A until you reach the desired health level.

In the Game Of The Year Edition, start by pressing B, then press R until you find the skills screen. Highlight the health bar, press Black, White(4), Black, then hold A and press B. Note: This code will become disabled if you switch screens; thus you may re-enter the cheat.

Enable the "Change health level", "Change magicka level", or "Change fatigue level" codes, and before you fill your health/magicka/fatigue up, while holding A and filling it, press B and exit. It will continue to rise and as it goes down, it will raise back up instantly. For example, start filling your health/magicka/fatigue, and press B before it is to the top, While still holding A and filling it, it will keep and always be full until you return to the menu.

To regenerate your Health, Magicka, or Fatigue without having to hold A, enable the code for the stat that you want to regenerate. While you are holding A, press B to get out of the screen. If done correctly, your stat should continue regenerating even while you are out of the menu screen. Do this with health, as whenever you get hit, your health automatically regenerates. If you go back into the menu screens and change to any other screen than your stats screen, you must enable the code for the stat to regenerate again. However, only enter the Black and White part of the codes. If you do the code for health and then want to do it with magicka or fatigue, just enter the Black and White part of the code; you do not have to hold A again unless you accidentally pressed A or loaded another game. This trick must be repeated every time you enter the game.

To get constant health in the Game Of The Year Edition, enable the "Change health level" code. After pressing A and exiting the menu, release A, go back in, highlight "Health", and press Black, White, Black(3), then exit the menu again. This will only work if you have lost some health. Note: When you activate the first part of the code it will not effect your health.

Use the following trick for easy Magika leveling. Enable the "Change magika level" code and go somewhere where your spells or conjured creatures will not bother anybody. This should be a safe location (preferably an empty house). Start casting the spell you want to level repeatedly by rapidly pressing R.

In order to have no weight, use the steps for unlimited spell effects using the Spell Feather with a magnitude from 100-100 on self for two seconds along with Soultrap for two seconds. After making the spell, cast it as many times as needed to get the desired encumbrance.

Note: Instead of using the previously described long process, get Skull Crusher (recommended) or a Feather Enchanted constant effect weapon and do the same process as to increase skill (hold L + R + X).

When you start to play the game, press Start and go to "Options". Once there, turn subtitles on. The subtitles will tell you what people say, even if they are not directing it at you. By doing this, you can see that the NPCs talk to themselves. The most common thing you might hear a person say is "Now, where is that slave?", however you can see some other comments. Arriel in the tradeshop in Syeda Neen will say "And so I was just standing there... naked." These NPCs will say some of the strangest things, but they usually say them when they are out of normal hearing range. This is why you need the subtitles, because it has a longer range and displays what is being said perfectly. Note: They do not do this all the time.

Use this trick to get things out of boxes far away, or most things laying out from extremely long distances. Get an Azura's Star, or Grand Soul Gem with a Golden Saint in it. The easiest way to get one of those Soul Gems and a Golden Saint spell (from the tower in Tel Branora). Go to a Spellmaker and make it last for fifteen or twenty seconds. This will make it work at a higher rate, and take less Magika. Then, catch the Soul and get a Telekinesis spell. Go to an Enchanter with a good sword or an Ebony Staff (recommended). Choose Telekinesis and put it low so it will not cost much. Change to constant effect, name it, then create. Equip the sword, hold A, then at the same time, hold L + R. Make it is done correctly so that you are always on the proper sword or weapon. In a few minutes, you will be able to hide in a corner unseen and steal from as far as you desired as well as lock pick objects. This does not work on humans, or some odd books.

Equip a bow, then any arrow. Hold Attack to pull the arrow back. Enter the inventory screen with the arrow still pulled back. You may now release Attack. Unequip the arrows and resume the game. It will now continue to shoot the arrow. After it fires, it will not count that arrow to be missing.
