Set Items
There are Set Items where wearing more pieces of an item set will convey more bonuses to your character.

Armor Swapping
Armor can't be swapped out (changed) while in combat. Other equipment such as weapons and accessories can be swapped out.

Linking Item Stats to Chat Text
You can create a link to your item in chat text, which is useful for showing it to people for trading purposes or just to share information about your item. Hold down "Shift" and left-click on the item while having your chat text typing box open. This will insert a link to that item. Whenever you see [itemname], you can click on that text to see the stats of the item. Trade channels are the only general chat channels that allow item links. You can also link to items in the auction house to show items for sale to your friends =].

Stacking
Some items are stackable. They will stack/combine automatically when you drag them over to your backpack. You can break up a stack of items by holding "Shift" and then left-clicking on the item. This will bring up a number box, which you can use to indicate how many items you want to take out of the stack.

"Made By <Playername>"
This is an item that was created using a trade skill. The name on the item is the name of the person that created the item.

+Damage vs. +Mana
Using Fireball as an example, you can cast more fireballs with the INT item, but the damage you do is greater with the DMG item. Overall you deal slightly less damage on a full mana bar but at an increased DPS using the DMG item.

+Chance Hit
Items which provide +hit chance counteracts the increased miss chance penalty of dual-wielding.
Instant Melee Attacks

The attack power bonus is multiplied by a fixed number pulled from the following table:

· Two-handed weapons: 3.3

· Daggers: 1.7

· All other one-handed weapons: 2.4

Many Epic (purple) quality items are more powerful than slower Superior (blue) weapons. At a given level requirement, epic quality weapons should always be more powerful than superior quality weapons. Please also note that all normal weapon swings will be completely unaffected by this change. The following abilities are affected by the design change: Sinister Strike, Ambush, Backstab, Whirlwind, Mortal Strike, and Overpower.

Cloaks & Helms
There are options that let you not display your helm and/or cloak on your character. These options will allow a player to wear a cloak or helm, but not have it show up in the game world. The check boxes to control this functionality are in the Options menu under "Interface Options." If you select to disable the display of these items other players will not see them as well.
