Siege in Heroes of Might and Magic I
As you know, the fortress wall occupies the fifth vertical line of the siege arena and consists of five destructible sections (towers). Each section provides protection to the defending units from ranged attacks and can be destroyed by one or two hits from a siege weapon (catapult). Only those defending units that are located behind the fortress wall receive the defense bonus, i.e., on the 6th or 7th vertical line. Note: a unit on the defending side that occupies two hexes is considered to be located on the n-th vertical line if its right hex is on that vertical line. The bonus is +4 to the Defense parameter and does not depend on the number of undamaged towers. Note: a partially destroyed section continues to provide the aforementioned bonus.
Before we consider the situations in which the defending side receives a bonus, let's examine the defensive ranged tower.
The Defensive Ranged Tower is considered an indestructible unit with a base attack of 2 and damage of (2-3)*k, where k depends on the number of buildings in the Castle: k = 5 + 4*m + n, where
m is the number of warrior dwellings built,
n is the number of other buildings, including the magic guild (always considered one building).
Furthermore, the attack of the ranged tower can be increased by:
- the attack of the defending Hero;
- the level of the magic guild.
Example: Yog (2-1-1-1) defends the Castle Besenji, which has a Hut, a Shack, and a Lair built, as well as a level 3 Magic Guild, a Well, and a Shipyard. Then the defensive ranged tower will have an attack of 2 (base) + 2 (Yog) + 3 (level 3 Magic Guild) = 7 and damage of (2-3)*(5 + 4*3 (three warrior buildings) + 3 (Well, Shipyard, and Magic Guild)) = (2-3)*(5 + 12 + 3) = 40-60.
Thus, the tower is another ranged unit that cannot be blocked or killed. Without a Hero in the Castle, in the worst case, its attack is 2 and damage is (2-3)*5 = 10-15, and in the best case, the attack is 6, and the damage is (2-3)*(5 + 4*6 + 5) = 68-102.
Note: The standard formula is used to calculate the damage, i.e., the tower's damage can be increased/decreased depending on the defense of the attacking unit.
Rules to determine whether a defending unit receives a defense bonus in each specific situation
Let's number the sections from 1 to 5 from top to bottom.
The defense bonus is NOT received:
You can skip this on the first reading
1) when the 1st section is destroyed:
- units behind the fortress wall, located on the 1st or 2nd horizontal line,
when attacked by ranged units from the 1st horizontal line.
2) when the 2nd section is destroyed:
- a unit behind the fortress wall, located on the 1st horizontal line, when attacked by ranged units from the 2nd or 3rd horizontal line;
- a unit behind the fortress wall, located on the 2nd horizontal line, when attacked by ranged units from the 2nd horizontal line;
- a unit behind the fortress wall, located on the 3rd horizontal line, when attacked by ranged units from the 1st or 2nd horizontal line;
- a unit behind the fortress wall, located on the 4th horizontal line, when attacked by ranged units from the 1st horizontal line.
3) when the 3rd section is destroyed:
- a unit behind the fortress wall, located on the 1st horizontal line, when attacked by ranged units from the 4th or 5th horizontal line;
- a unit behind the fortress wall, located on the 2nd horizontal line, when attacked by ranged units from the 3rd or 4th horizontal line;
- a unit behind the fortress wall, located on the 3rd horizontal line, when attacked by ranged units from the 3rd horizontal line;
- a unit behind the fortress wall, located on the 4th horizontal line, when attacked by ranged units from the 2nd or 3rd horizontal line;
- a unit behind the fortress wall, located on the 5th horizontal line, when attacked by ranged units from the 1st or 2nd horizontal line.
4) when the 4th section is destroyed:
- a unit behind the fortress wall, located on the 2nd horizontal line, when attacked by ranged units from the 5th horizontal line;
- a unit behind the fortress wall, located on the 3rd horizontal line, when attacked by ranged units from the 4th or 5th horizontal line;
- a unit behind the fortress wall, located on the 4th horizontal line, when attacked by ranged units from the 4th horizontal line;
- a unit behind the fortress wall, located on the 5th horizontal line, when attacked by ranged units from the 3rd or 4th horizontal line.
5) when the 5th section is destroyed:
- units behind the fortress wall, located on the 4th or 5th horizontal line, when attacked by ranged units from the 5th horizontal line.
Of course, the penalty disappears (regardless of the presence of walls) if your ranged units attack while located on the (5-7)th vertical line, and also if the defending units are not behind the fortress wall, i.e., on the (1-5)th vertical line.
In other words:
Let the ranged unit be on the horizontal line with number N and any vertical line V < 5, then:
1) if the tower on this horizontal line is destroyed, then the ranged unit attacks without penalty against units opposite, above, and below (N - 1, N, N + 1).
2) if the tower is destroyed on one horizontal line above or below the ranged unit, then the ranged unit attacks without penalty against units on the two horizontal lines following the destroyed tower with numbers:
a) N - 2 and N - 3, if the destroyed section is above the ranged unit;
b) N + 2 and N + 3, if the destroyed section is below the ranged unit.
3) when the central tower is destroyed, the extreme ranged units (1st and 5th horizontal line) can additionally attack units on the 5th and 1st horizontal lines without penalty, respectively.
4) in all other cases, ranged units attack with a penalty.
The first screenshot demonstrates rule #1.
The second screenshot demonstrates rule #2.
In the third screenshot, the central unit of hydras, strangely enough, receives a +4 bonus to defense (rule #4), and the top one does not (rule #2)!
In screenshot #4:
a) trolls attack without penalty only the hydras on the 5th horizontal line (rule #3, no central tower);
b) archers attack without penalty units #2, 3, 4 according to rule #1 and unit #5 according to rule #2;
c) centaurs attack without penalty unit #1 according to rule #3 and units #2, 3 according to rule #2;
d) druids in this situation attack all enemy units without penalty (units #1, 2 according to rule #2; units #3, 4, 5 according to rule #1);
e) orcs attack without penalty only the hydras #4 and #5 (rule #2).
In the fifth screenshot, none of the defending units receive a bonus, because the druids are already "on their territory" (5th vertical line). If they were one vertical line to the left, the goblins and orcs would feel much better, but the hydras would still not receive a bonus (rule #1).
