Ethereal

Ethereal, sometimes referred to as ghost form, is a type of status effect that makes a target immune to all physical damage, while also disarming them. It also reduces their magic resistance, causing them to take additional magical damage. Afflicted units are able to control every other aspect of their character.

Ethereal units cannot be directly attacked, not even with manually cast active attack modifiers like. They are fully affected by spells, blocking physical damage but not preventing their other effects. For example, cannot damage ethereal units, but still stuns and slows them. Ethereal state does not dispel anything.
