Void Warheads

"Concentrating Void elements within Missile & Torpedo weapons, the payload increases the area of explosion, and damage to armor health but has less impact against shields."

General
Void Warheads are a fusion of AM Warheads and Blister Rounds designed for PvP combat. They are limited to Marauder Hulls and only affect Missile and Torpedo weapons.

Advantages
Void Warheads provide a bonus to armor damage, which is useful against many Xeno Division Hulls and A.X.I.S. Hulls due to the popularity of heavy armor builds. They are also great against modules which are comprised almost entirely of armor.

Disadvantages
Void Warheads increase the explosion radius of your weapons by a proportionate amount. However, this is actually weaker than AM Warheads unless your weapons have at least 500 m AoE by default.

Void Warheads suffer a penalty to shield damage, and are therefore weak against the occasional Harmonic Exophase Shield and Circuit Shield fleet.

Trivia

 * Void Warheads was originally available on the Vanquisher Carrier, which is not intended. The second January 2019 update corrected the issue; players who had it equipped were compensated according to this thread.
