^ Kinetic damage is best, EM and thermal are both ~75% as effective as kinetic but EM is better against shields and Mordu's ships have active shields so it is better overall. EMP is best projectiles to use.
^ Rogue Drones have a tendency to vary wildly in what damage type they deal and are vulnerable to. Low-level missions seem to lean towards EM/Thermal while high-level missions lean towards Explosive/Kinetic. Consult mission reports about the specific mission or exploration site before undocking.
^ This refers to CONCORD enemies found in certain missions (particularly in low- and null-sec). CONCORD ships patrolling high-sec are invincible, so the damage types they do is not relevant.
^ a b c d e f "(Omni)" means that the ships do all damage types equally, or are equally vulnerable to all damage types.
^ Em/Th approx 75% as e
