Luck is a combat variable, that may cause a creature stack to do additional damage. As can be seen from the table on the right, there are three levels in luck modifier: positive (+1), good (+2) and excellent (+3). Luck can also be neutral (zero), which means that a creature stack cannot get a "lucky strike". Creature stack's luck modifier depends mainly on hero's luck status, but can also be affected by spells (Fortune, Misfortune) or creature abilities (e.g. Devils). Additionally, 死亡陰影 expansion introduced magical terrains that can affect luck modifiers. Hero's luck depends on equipped artifacts, possible luck secondary skill and/or visited Adventure Map locations.
There are several references in the game, that receiving luck during combat causes double damage. However, this is not entirely accurate because the damage is not simply multiplied by two when lucky strike appears. Receiving luck when attacking means that the creature stack does additional base damage on top of the regular damage. This additional "lucky damage" is then affected by the various factors as explained in damage formula. Thus, the final damage is not actually doubled.
