Ineffectiveness Rule

Any strike from a ship with a weapon rating that is less than or equal to 1% of the shielding capacity of the target is absorbed with no effect on the target. As an example, suppose a player with a Weapons Tech of 12 attacks a player with a Shield Tech of 9, and in the battle one of the attacker's Artemis Fighters targets the defender's Large Decoy. The fighter would have a weapon rating of 110 (50 + 5 * 12). The Large Decoy would have shield rating of 19,000 (10,000 + 1,000 * 9). Since 110 is less than 190 (1% of 19,000), the Artemis Fighter would do no damage; that shot is ineffective. Furthermore, it is essentially impossible that an attacker could research their Weapons Tech high enough that an Artemis would ever damage a Large Decoy. However, some units have base weapons ratings that are equal to 1% of other units' base shield ratings; in these cases the respective weapon and shield tech levels come into play.

Shots by the following ships are always effective: Erebus Fighter, Moros Battleship, Prometheus Destroyer, Zeus.

Shots against the following units are always effective (base shield less than 100): Missile Battery, Laser Cannon, Hermes Probe, Helios Solar Satellite, Atlas Cargo, Dionysus Recycler, Hercules Cargo, Charon Transport, Artemis Fighter, Apollo Fighter, Poseidon Cruiser.

Defenses have relatively high weapons ratings; their shots are effective against all attack ships, with the exception that “fodder” defenses (Missile Battery, Laser Cannon, Pulse Cannon, and Particle Cannon) are ineffective against Zeus.
