Damage Modification:
Locate the Default.ini in your \Program Files\Thief - Deadly Shadows\System directory and open it with a text editor.

Be sure you make a backup of this file before you start modifying it.

Locate the following section:

Difficulty_AIToPlayerDamage_Mult_Easy=0.5
Difficulty_AIToPlayerDamage_Mult_Normal=1.0
Difficulty_AIToPlayerDamage_Mult_Hard=1.25
Difficulty_AIToPlayerDamage_Mult_Expert=1.5

Change the AI damage to player multiplier to 0.0 for almost no damage (note that a base damage still applies) to you; you may want to reduce the hit points of the enemies as well. Just a warning not to reduce the hit point multiplier of the AI to 0.0 or any hit (including a blackjack blow) will kill an enemy instantly.

Free Water Arrows:
You can get free water arrows in the training mission (which carries over to your subsequent missions) by waiting by the douse the torch exercise for water crystals to keep respawning. Before you leave the Blue Heron Inn forever, you may want to take your fill of 25 water arrows, which will go a long way in helping you keep shopping costs down.

Item Maximums:
Gear and items are bought to be used in Thief 3. Don't go to great lengths to save items if you think they can help you stay alive and undiscovered, but don't waste them on lone guards or civilians who cannot fight back.

On normal, the maximum gear Garrett may carry is:
Health Potion = 10
Broadhead arrows = 30
Noisemakers = 5
Water Arrows = 25
Moss Arrows = 20
Gas Arrows = 5
Fire Arrows = 15
Flash Bombs = 20
Explosive Mine = 5
Gas Bomb = 5
Oil Flask = 5

Metal Age Nightvision:
Although shadows are important to hide Garrett, sometimes it can too dark to see while hiding. Crank up the Gamma/Brightness correction in your options menu to see the surroundings while remaining hidden.
