Battle system

At the start of the game, the main efforts of the players are focused on economic development, i.e. improvement of buildings, resource extraction, takeover of vacant castles, etc. However, subsequently, more attention is being paid to warfare. Eventually, any game comes down to confrontation between two largest unions on the server; therefore, it is impossible to win the game without knowing battle system.

If you are new to the game, we strongly recommend you to read our article “Units: Appropriate Defense and Attack”. It describes the existing units and intended purposes of each soldier.

Battle rounds

Lords and Knights: Battle System

Any combat consists of battle rounds. One round lasts 10 minutes. If at the end of the round there are 100 or more soldiers participating from each side (transport units are not taken into account), all the participants of the battle will have only 50% from the calculated casualties and they will move on to the next round. Replacing the losses of soldiers after each round, you can prolong the battle indefinitely. This principle is the basis for construction of protection bridges.

If the combat takes place in a fortress, there shall be at least 500 units from each side to continue the battle. In the town it is necessary to have not less than 2500 units.

Every server has its individual settings that may differ from configuration of other servers. The minimum number of soldiers for a round mentioned above is true only for standard game worlds constituting the vast majority. To extend a combat on battle servers, a larger number of units is required: 250 (1250 for a fortress, 6250 for a town) or 500 (2500 for a fortress, 12500 for a town) depending on configuration of a particular server. All calculations given further in this article will be true for a common castle in a standard game world.

If by the end of the round at least one of the battling parties has less than 100 soldiers, this round may become the last one. However, we need to state that availability of less than 100 units from one side does not necessarily mean the inevitable end of the battle in the current round. Combat round becomes final only when one of the armies is completely destroyed.

Calculation of casualties

A soldier has three characteristics that determine his strength against each branch of military force (infantry, cavalry and artillery). The power of the army is simply calculated as sum of combat parameters of all units. Eventually, the strength of contending armies is compared by military branches and determined by casualties of battle participants. Let’s take a closer look how to do it using a specific example.

We will suppose that the following armies fight for a castle.

Attacking forces
Swordsman Lancer Horseman
100 pcs. 90 pcs.
Weapon manufacturing (5% infantry offense)
Defending forces
Crossbowman Armoured Horseman
45 pcs. 55 pcs.
Fortifications 16 level (80% unit defense)

Table 1. Initial data

Combat parameters of soldiers can be enhanced as a result of science study and construction of buildings in their native castle. This have particular impact on defensive units: upon full improvement of fortifications and study of sciences, their protection parameters increase more than two times. Therefore, it is important to keep in mind that units of the same type but of different castles may have widely different characteristics.

In Table 2 you may see characteristics of soldiers from the current example without regard to enhancing bonuses.

Attacking forces
Swordsman 57 39 24
Lancer Horseman 57 33 99
Cavalry Infantry Artillery
Defending forces
Crossbowman 31 87 57
Armoured Horseman 35 26 57
Cavalry Infantry Artillery

Table 2. Basic characteristics of soldiers

The parameters of soldiers after application of increasing factors from the Table 1 are shown below.

Attacking forces
Swordsman 5% 60 41 25
Lancer Horseman 57 33 99
Bonus Cavalry Infantry Artillery
Defending forces
Crossbowman 80% 56 157 103
Armoured Horseman 80% 63 47 103
Bonus Cavalry Infantry Artillery

Table 3. Soldiers’ characteristics with account of enhancing bonuses (the values are rounded to the nearest whole number)

After application of bonuses, combat characteristics of each type of soldiers are multiplied by their number and then added. Besides, the scores obtained from works (See Table 4) are added to the defending army.

Attacking forces
Swordsman 100 6000 4100 2500
Lancer Horseman 90 5130 2970 8910
 
Qty. Cavalry Infantry Artillery
Defending forces
Crossbowman 45 2520 7065 4635
Armoured Horseman 55 3465 2585 5665
Fortifications 750 750 750
Qty. Cavalry Infantry Artillery

Table 4. Summarized power of combatant armies

Casualties of the parties are calculated separately for each military branch. The party scoring fewer battling points incurs 100% casualties. Soldiers’ survival rate of the winning party shall be calculated using the following formula: 100% * [scores of the defeated party] / [scores of the party that won].

Attackers Cavalry Defenders
11 130 Points 6 735
60% Losses 100%
Attackers Infantry Defenders
7 070 Points 10 400
100% Losses 68%
Attackers Artillery Defenders
8 910 Points 11 500
96% Losses 100%

Table 5. Casualties of battle participants in regard of military branches (as if the current round was the last one)

Nevertheless, as already mentioned earlier, if by the end of the round each party has not less than 100 soldiers, casualties of both participants of the battle halve and they move on to the next round. Our example is exactly such case, so the losses among soldiers will be halved (See Table 6).

Attackers Cavalry Defenders
30% Losses 50%
Attackers Infantry Defenders
50% Losses 34%
Attackers Artillery Defenders
48% Losses 50%

Table 6. Casualties of battle participants in regard of military branches (final result)

The obtained casualty rate among military brunches applies to corresponding units and there results the number of soldiers that have moved on to the next round of the battle (See Table 7).

Attacking forces
Swordsman 50% 50 pcs. 50 pcs.
Lancer Horseman 30% 27 pcs. 63 pcs.
Losses, % Losses, qty. Survivors, qty.
Attacking forces
Crossbowman 48% 23 pcs. 23 pcs.
Armoured Horseman 50% 28 pcs. 28 pcs.
Losses, % Losses, qty. Survivors, qty.

Table 7. Casualties among soldiers

The defending army has less than 100 units, and if it does not make up for the losses occurred in the previous round, the next round may become the last one. In our case, we will take that the defending castle was left behind and only 56 survived soldiers will participate in the next round.

We will skip the part of intermediate calculations for the second round and will show the table where we tallied up the scores.

On our website you can find a calculator of battles, it is free to use. In addition to the final result, it also reflects all intermediate calculations mentioned in the article. You may use it to better understand this material.

Attackers Cavalry Defenders
6 591 Points 3 802
58% Losses 100%
Attackers Infantry Defenders
4 129 Points 5 677
100% Losses 73%
Attackers Artillery Defenders
7 487 Points 6 003
80% Losses 100%

Table 8. Casualties of battle participants in regard of military branches for the second round.

As can be seen from this table, the defending army will lose all cavalry units and artillery units in this round and thus it will be completely destroyed. The second round becomes final. The battle is over.

Attacking army is the winner.
