During the course of your adventures, you will gather a good number of items. Some of them can be used (potions, torches, magic scrolls, etc.), others can be equipped (weapons, armors, rings, etc.). Items that are used vanish from your backpack when they are exhausted. Items that can be equipped vanish from your backpack and show up in your status box when they are equipped, and return to your backpack when they are unequipped.
Some items can be used more than once. They have a number of charges which are used up every time the item is double-clicked on. Some other items also have attribute or level requirements. If you do not meet these requirements, you will not be able to use or equip these items and they will remain in your backpack.
Reminder: The equipment you have equipped on your body can be seen in the statistic window (Ctrl-S) while all the rest of your goods are stored in your backpack (Ctrl-I). You can always identify items by right-clicking your mouse button when the cursor is over the selected item. This works for items on the ground or in your backpack.
Items that are left on the ground can be picked up. Simply move your mouse cursor until the item's outline shows up, then click with your left mouse button. The item will disappear from sight and reappear in your backpack (Ctrl-I).
If you want to drop an item on the ground, you must first open your backpack, move the mouse cursor over the item, hold the left mouse button and drag the item outside of the backpack onto the location where you want to drop it. Once you let go of the mouse button, the item will remain on the ground.
To use a particular item, you must double-click on it using the left mouse button. If the item has multiple charges, it will remain in your backpack until all the charges are exhausted. Every use of the item burns up one charge. Most items (potions, torches, etc.) have only one charge and vanish as soon as they are used.
Equipping & Un-Equipping Items
To equip an item, you will have to open both your backpack (Ctrl-I) and the statistic window (Ctrl-S). Left-click on the desired item you wish to equip in your backpack and drag it on the black silhouette in the statistic window (see image below). The item will automatically equip itself where it should be (torso, hand, feet, head, etc.). If you do not have the proper requirement(s) for wearing a particular piece of armor or to wield a weapon, it will return into your backpack and an system message will appear at the bottom of your screen.
If you wish to unequip a particular item, open your statistic window (Ctrl-S), double-click on it and it will automatically return into your backpack (unless it is a cursed item, in which case it will remain equipped). Note that the Gem of Destiny cannot be unequipped (anyway, why would you want to remove an item that saves your life?).
Partial Items Listing & Requirements
This does not include all the items available in the game, but should be enough to get you started and help you plan how you can spend your attribute points every time you level. Note that because some last-minute changes may have been made to the game, not all of these items may still be available or accurate.
