Harmonic Siege Casing

"Upgraded Siege Casing to include Harmonic Siege bonuses, Siege Casing is designed for base attacks, improving projectile speed and targeting module weak points, with protection from oncoming projectile damage."

General
The Harmonic Siege Casing is a Siege Casing with an added Harmonic Siege bonus. It can only be equipped on T6.5 destroyers and above.

Advantages
The Harmonic Siege Casing shares the same advantages as the regular Siege Casing. Its additional Harmonic bonus enables your entire fleet to deal more damage to enemy modules.

Note that it cannot be stacked with other Siege Casing variants, unlike the Beam Capacitor.

Disadvantages
The Harmonic Siege Casing takes up significantly more mass than the regular version; this is not a problem unless your fleet is completely FvF-oriented.

Trivia

 * Harmonic Siege Casing was not unlocked to Umbra and Pharmakon when the respective factions were released. This was fixed in the late February 2019 update.
 * Along with other T6.5 equipment, this item's build time was significantly reduced during the late April 2019 update as summarized here.
 * Its repair time was nullified as a result of the early February 2021 update, which updated the repair time of all Tier 6 ships to be invariant to equipment.
