Diffuser Shield

"The Diffuser Shield is a ship shield that takes reduced damage from Energy weapons and recharges to full strength over time."

General
The Diffuser Shield is an advanced Energy ship shield that can start replenishing its energy reserves after several seconds without interruption.

Note that once fully depleted, the shield is useless for the remainder of the battle and cannot recharge.

Advantages
Diffuser Shields can potentially block massive amounts of damage, provided that they get the chance to regenerate after each volley.

Regenerating shields are excellent for shield-switching tactics, where a healthy ship protects a damaged ship (most commonly through ship blocking), buying time for the damaged ship to fully regain its shields. They are also good for intermittent combat such as sniper attacks and battleship fights, where shields often get the chance to regenerate between each round.

Diffuser Shields have the most shield energy out of the three regular regenerating shields, and are best suited to tank Alien, Plasma and Void damage, which none of them can resist.

Disadvantages
Diffuser Shields have poor mass efficiency compared to the Spectral Shield without the chance to recharge. Therefore, if your fleet is designed to blitz enemy ships or otherwise engage them in close combat, it is not recommended to use this shield as the enemy can easily overwhelm them in a single volley.

Trivia

 * Hulls with active Diffuser Shields glow yellow, similar to the Spectral Shield.
