A unique item is an item whose name is in gold. Often, these items are better versions of their normal, white named counterparts, with a various multitude of modifications (buffs), that make the item better than what one might find normally. If something is a Gladius (a white named item, Sword), there is a Unique version of it with many abilities that make it better (in this case, Bloodletter Gladius). Requirements are often equal to, or lower.
And Elite item is another form of a white named item, except better. If one finds a Long Sword, there is another form of that item, except better, having higher requirements for a better quality weapon, and in this case, something called a Tusk Sword. Elite items also have their own, Unique forms.
A Rune is an item in which you insert your items with. After they have been placed, they cannot be removed, except by a special use, which, ironically, requires another rune. Runes have word values, and special modifications and benefits that they can add to an item. If you spell a Runeword correctly by placing Runes in the correct order, a large number of modifications will show up on the item, turning it both into a Unique item, and have the proper spelling. Some are more useful than others.
