When troops are sent to attack (by normal attack or raid) a village, combat takes place. In game terms, the attacking troops are mixing it up with the defenders stationed there, which includes the local troops, any reinforcements, and some local residents (see below). Swords clash, people die, certain special troops may perform some special maneuvers, and after it all, surviving offensive troops will grab some loot and go home.
In metagame terms, combat is a mathematical comparison of the sum total attack strength of the offensive troops (
) against the sum total defense strength of the defending troops (
and
, depending on the type of attackers). Blacksmith levels of all the offensive troops, Armory levels of all the defending troops, wall level and type, presence of a Residence or Palace, relative size of attacker's village vs. defender's village (is it total player's size, or village's size?), attackers' types (infantry or cavalry), and possibly other unknown factors, are all taken into account in this calculation. After the comparison, casualties are assigned, based on the type of attack (normal or raid). If any attackers survive, and if they have any carrying capacity, and the defending village has any available resources, the attackers will take some resources and return to their village.
Note that even an empty, undeveloped village is not undefended; it has some innate defenses of its own (estimated by some at 75
/75
). (Consider this the peasants grabbing torches and pitchforks to defend their homes.) Thus, the minimum party necessary to attack a "defenseless" village without incurring a casualty depends upon the attack strength of the unit, as with normal combat. Thus a phalanx, with an attack strength of 15, requires at least 13 (some say 12) units involved in an attack in order to survive without losses; while units with greater attack strength can survive with far fewer attackers. The Palace and Residence are also believed to increase this innate defense number (think of some permanently-garrisoned royal guards joining the above peasants). Also note, it is believed these innate defense numbers are affected by the village's wall.
During, or immediately before or after, combat is when certain troop types use their special abilities:
- Rams sent in a normal attack will attempt to destroy or reduce the level of a village's wall.
- Catapults sent in a normal attack will attempt to destroy or reduce the level of a building.
- Senators/Chiefs/Chieftains sent in a normal attack will attempt to lower the loyalty of a village.
- Scouts sent in either a normal attack or a raid, in any number but with no other type of troop, will avoid combat in order to spy on the target village.
