Item Database:Ammunition & Charges:Hybrid Charges
All this data is potentially out of date, and should be taken with a truckload of salt
Hybrid ammunition uses hybrid plasma-shell rounds to deal damage. They are used primarily by Caldari and Gallente ships. Their combination of Kinetic and Thermal damages makes them moderately effective against both shields and armor.
Hybrid charges are the only kind of weapon that require both ammunition and energy from your capacitor. They have an advantage of that they do not use as much capacitor's energy as frequency crystals, while they also have a more versatile spread of available ranges then projectile charges do.
