Invulnerability Drive

Your ship is equipped with an experimental device which can render it immune to all damage. As an action, a crewmember can activate the drive. Once activated, the drive lasts for 1d4 rounds, granting the following benefits:

• Your ship is immune to all damage.
• Your ship's flying speed is reduced by half.
• Your ship's turning speed is doubled.

A crewmember can end this effect at any time, no action required. When the effect ends, the crewmember must make a Destruction saving throw. On a failure, the ship suffers 1 level of system damage. Once this feature has been used, it can't be used again until the ship undergoes refitting.
