Start with Onyx Sword
After you have completed the game once and have saved the game with the Onyx Sword in your possession (for example, with the human), start a new game with a new character (for example, the dwarf) and save. Import the human, drop the Onyx Sword and any other good items, then import the dwarf and pick them up. Note you can do this with any character and any weapon.
Play as Drizzt
Successfully complete the game under the extreme difficulty setting.
Alternately, choose to play The Gauntlet. You will start as Drizzt. Enable the "Invincibility" cheat and complete The Gauntlet within 15 minutes. .At the end where you face the Onyx Golem, use the "Level warp" cheat to go to the Tavern. You can now play the game as Drizzt. Note: You cannot equip any other sword than the ones he has during The Gauntlet. Import a new character into the game and give him the Onyx Sword, since Drizzt cannot use it.
If you have not completed the game yet, enable the "Cheat mode" code, then level warp to the to the bottom (Tower). Defeat Eldrith, go to the Gauntlet level, then level warp anywhere desired.
Duplicate items
Save the game, then drop the items to be duplicated from the inventory of your current character. Press [Start] and choose to change your character. Import your character from the previously saved game. The game will bring in your character with all items in inventory at the time of your save, and allow you to collect the duplicates that are on the ground.
Save the game and use a Recall Potion to return to the Elfsong Tavern. Drop all your expensive items, then import your saved player. Pick your items up and sell them. You can do this as many times as needed, have to save each time before you import again or you will lose the gold you have made.
Easy items
If you have a high level character with many good items that you would like a new character to have, start a new game with the new character. Then, load the character with all the items as the second player. Then, drop the desired items on the floor to allow the new character to pick them up. Equip everything and sell off things that are not needed. Then, save the game and restart the Xbox. Play a new game with a new character and load the other new character (that has all the items) as the main character.
Getting good items
Note: This is best done in the Onyx Tower. Before you open a treasure chest or search a weapon rack, save the game. Then, open the treasure chest or search the weapon rack. If you do not like what you get, reload from the last save and try again. Each time that you try, you will get a different item.
Easy money
This trick can be used at any point in the game. Save the game near a shop. Drop all your expensive items, then load your saved character to the same location. After the loading screen, pick up all your items and sell them. Do this again in the exact same order. You will get a lot of money.
Use the "Duplicate Items" trick with your most expensive item or weapon. Keep duplicating it until you cannot hold anymore. Sell the duplicates and buy the most expensive weapon you can afford. Duplicate these even more expensive weapons and sell them back. Keep doing this to build an unlimited amount of gold. It gets easier when you can afford the more expensive weapons.
Enable the "Cheat mode" and "Invincibility" codes and go to The Gauntlet level. Get the Onyx Sword, sell it, and repeat.
This does not award you too much money, but in the beginning of the game every coin counts. When you sell arrows, the value is the same, whether you are selling one arrow or a full set of twenty. This trick only works if you have a bow, as this is the only way to break up a set of arrows. If you are using the bow, then sell the used arrows (those of less than twenty), then immediately repurchase a set. This trick works best if you have less than 100 arrows, as the vendors only buy the last set of arrows. For example, if you have 1103 arrows, it would not be worth the time to go through all your arrows to get to your used set.
Easy experience
Note: You must constantly save your game in order to do this trick. At any time when you encounter a Boss, immediately save the game to a new file after defeating them. Press [Start] and load the game file that was saved immediately before you fought the Boss. After the game has loaded, press [Start] and go to "Characters". Import the character from the file that was saved when you defeated the Boss. You will now have a character with more experience, but will be able to fight the Boss again which results in lots of experience. Keep doing this every time you defeat the Boss to gain levels faster.
After you are in to the game a short amount of time, talk to everyone in the tavern for easy experience. Also check periodically; as you complete more of the first part, there is more experience to be gained in the tavern.
Use the "Level warp" cheat to go between Acts. Every time you go to another Act, all enemies and Bosses will respawn. Warp to the Throne Room, Ice Cave 3, and the Tower before the final stage and defeat those Bosses. Repeat this to level up quickly.
When in the crypts and fighting the zombies, you can get double experience. If there is a zombie with two arms, slash him once without cutting his arm. Then, kill him by arrows or spells. His top half will come off and chase after you. Kill it, and you will get experience as if you killed two zombies.
Once you have unlocked the Extreme mode, create a two player game on easy difficulty. Then create a two player game on extreme mode and import the two easy mode characters into it. Use the "Level warp" and "invulnerability" cheats and go to "towerh". Head down to the "Black Forge" level and defeat the Onyx Golem. The character who kills the Golem will become level 32, and the other will become level 26.
Start an extreme difficulty file, then load a first level character from an easy difficulty game. Have them kill the Onyx Golem, but do not spend the feat points as they level up to 40. Once the character has finished leveling up, do the "Super 20th level character" cheat. The feat points will transfer over, but the hit points and energy will be at 1000/1000. Your character should now have max stats and enough feats and magic points to max out all feats and magic.
Carry more items
The game only checks how much you can carry when buying and picking up items. You can put on Rings Of Strength and an Amulet Of Strength, pick up man items, then take off the strength items and put on Rings Of Constitution for more HP or other rings and amulets to boost other stats. This works well when duplicating Extra Healing Potions so you can carry a large number of them through tough areas and to face end Bosses.
Lighter load
When you first begin the game, you are dressed with boots, gloves, and clothes - none of which have any defense value. Sell them to lighten your load by about 15 lbs. You may look a little funny without any clothes on, but your defense (Armor Class) will have remained the same.
Move faster
To move faster, you can jump everywhere instead of walking. It will make the journey about one and a half times faster.
Easy targeting with a ranged weapon
When using a ranged weapon such as a crossbow, press the [C-stick] [Forward], then rotate it around to aim, all the time leaving it on its furthest axis.
Safe stash
If you drop items in a place populated by friendly people (in other words, people you are not allowed to attack, such as in the Elfsong Tavern), some if not all of the items dropped will be gone if you leave the screen and return later. However, items left in the company of monsters (such as in the Sewers) will always be there when you return. Apparently, the monsters are more trustworthy than the patrons of Baldur's Gate.
Resurrection in multi-player mode
If a player dies during multi-player mode, have the surviving player go the previous save point. Walk in the light surrounding the save point and they will be brought back. The character will be resurrected with all items, but at half hit points.
Sorcerer supermodel
Choose the Elven Sorcerer, then talk to the bar owner and finish. When you are done, go to the menu and remove her clothes to see her in her underwear.
Crypt vase combination
In level 1 of The Crypt, the combination for the vases are: blue, green, yellow.
Freeze ghosts
When you are in the Crypts or Hall Of Remembrance as Adrianna or Drizzt, use the Ball Of Ice. Wait until a ghost is next to a wall then shoot it at the wall. The ghost will freeze and keep going straight without moving.
Act 2: Easy experience and gold
After defeating the Drow dark elf in Act 2, talk to the Dwarf in the cellar. Then, recall to town and immediately save the game. Talk to the another dwarf other than the one where you can buy and sell. He will thank you and give you 2000 experience and 3000 gold. Save this as a new game. Load the old game and import your character from the new game. Repeat this as many times as desired.
Best sword
The best sword is not the Onyx Blade. It is the Shocking Burst Adamantine Bastard Sword +3. It does 48-180 damage, as well as electrical damage.
The Shock Adamantine Great Sword +3 does 56-204 damage. It can be found in the Onyx Tower in extreme mode. You cannot buy this sword.
The best weapon found so far is the Shocking Burst Adamantine Great Sword of Defense +5. The damage is 64-212 and can be found in the Onyx Tower. You cannot buy this weapon.
Recall back to saved point
A simple way to transport yourself from any level is to use the Recall Potion. The manual states that you can use the Recall spell to warp you to the safety of the tavern, but it does not mention that if use it a second time from the tavern, it will warp you back to your last saved point. This can save lots of time and aggravation, and can be useful to unload items, sell them off, or load up on upgrades without having to work your way back to the same level point after you are done.
