The Harmonic Exophase Shield is a powerful ship shield that protects against the 4 most common damage types in combat - Energy, Explosive, Kinetic, as well as Alien Damage. However, it is restricted to A.X.I.S. Hulls or better, and has an insanely long repair time.

Strategy and Setup


Harmonic Exophase Shields can vastly improve the durability of your ships, carrying lots of shield energy in addition to a Harmonic Shield bonus.

They are extremely XP-efficient especially at level III, costing only around half the XP of a Metaphase Shield III while providing even more protection.


Harmonic Exophase Shields are not effective against Plasma Damage, a common damage type used in advanced Alien Event Targets. They also cannot resist Void Damage that is dealt by Marauder Hulls.

To add insult to injury, this shield is incredibly repair-inefficient: each point of shield energy gives you 1.75 seconds of repair time. This means that you will get more repair time overall, especially if the enemy is using weapons with enhanced shield bypass such as Eclipse Drivers. Most Alien Event Targets carry weapons with built-in shield bypass as well. Note that this is partially counteracted by the extra shield energy provided by the Harmonic Shield bonus.


  • Hulls with active Harmonic Exophase Shields glow with many colors at once.
  • The Harmonic Exophase Shield originally had a 1:2.5 energy to repair ratio prior to the early September 2017 update.
