Invulnerability

Impenetrable.

Invulnerability is a status effect that renders the target completely immune to most disables and damage, with a few exceptions. Invulnerable units cannot be targeted by attacks or abilities, and will often have their health bar temporarily hidden. Invulnerability is often only granted for very short periods of time. Banish, Cyclone, and a few Sleep affects can make units invulnerable for the duration. Most wards are also invulnerable.
