There are currently no known associations with the word "Ethereal" and gameplay mechanics.

In the older [[Diablo games]], "Ethereal" is primarily associated with the attribute of some {{iw|items Diablo II items}} that are called specifically {{iw|ethereal ethereal}}. These items generally have greater quality than other items, like striking harder, but can not be repaired from wear and tear. There are ways to make an item invulnerable, which is the only way to use ethereal item longer than the durability would allow.
