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. If attack projectiles of ranged heroes are already flying, their effects get completely blocked when the target is ethereal on contact. This includes any attack modifier effect like damage and debuffs.

Ethereal units are normally and fully affected by spells. However, physical damage is blocked. For example, cannot damage ethereal units, but still stuns and slows them. Ethereal state does not dispel anything.
