Spectral Fields are resistant to energy type weapons, and take 50% reduced damage from them. They are the first type of field players are likely to research. Compared to Shockwave and Deflector fields, they have the highest shield energy, as well as the highest mass.
These fields are designed to be used as a blitz counter, which are high speed, close range ships with stronger weapons, they strike fast and hard, usually attacking the bridge first. Due to the fact that energy weapons are typically used at close-range, they are more prevalent weapon types in blitz fleets. They are excellent against high-damage energy weapons such as the Burst rays, Pulse raysDisruptor rays and Thermal beams, as well as a fairly good defence against Fighter squadrons.
Due to the fact that base defences do not scale well with the firepower of ship weapons and fleet strength towards the higher levels, Spectral fields become obsolete after mid level stages of the game. Players are recommended to equip the more versatile Metaphase field instead.
