Invulnerability

Invulnerability is a keyword that was introduced in the Superman, Man of Steel expansion.

"Invulnerability" is a keyword that represents a continuous power that functions in the in-play zone. As characters with invulnerability become stunned, they cause their controller no stun endurance loss, rather than stun endurance loss equal to their recruit costs.

If a character would simultaneously lose invulnerability and become stunned, they cause their controller no stun endurance loss.
