Attacking & Defending

Military Efficiency

Base Military Efficiency

Base Military Efficiency = ( 33 + 67 * ( Effective Wage Rate / 100 ) ^0.25 ) * Ruby Dragon * Multi-Attack Protection Bonus

• Rounded to one decimal point, it should return the most accurate values. Effective Wage Rate lies between 20% (77.8% Efficiency) to 200% (112.7% Efficiency).
• While wages can be changed instantly, the effective wage rate used for base military efficiency changes slowly per tick. It takes approximately 96hrs to go from 20% wages to max at 200% wages.
• Effective Wage Rate Formula = (Final Wage Rate - Previous Wage Rate)* 0.05 - Previous Wage Rate

• 96 Hour Wage Rate Chart: ME Chart

Change in Effective Wage Rate = 0.05 * (Wage Rate Paid - Effective Wage Rate)

• If wages were not fully paid in the previous tick, Wage Rate Paid will be set at minimum regardless of the amount of wages actually paid.

Offensive Military Efficiency

OME = (Base Military Efficiency + Training Grounds Bonus + Honor Bonus) * Science Bonus * Race Bonus * Personality Bonus * Fanaticism * Bloodlust * Ritual

Defensive Military Efficiency

DME = (Base Military Efficiency + Forts Bonus + Honor Bonus) * Science Bonus * Race Bonus * Personality Bonus * Minor Protection * Greater Protection * Fanaticism * Plague * Ritual

Attacking

Raw Offense

Raw Off = (Soldiers * (Soldier Off value + Aggression)) + (Offensive Specs * Off Spec Attack value) + (Elites * Elite Attack value) + (Horses * War Horse Attack value) + [(Mercs * Attack Value + Prisoners * Attack Value)]

Modified Offense

Mod Off = Raw Offense * (OME + General Bonus)

Condition	Modifier
OME	check your Military Advisor
General Bonus	+5% per additional general over 1

Attack Times

Attack Time = Base Attack Time * Race Bonus * Personality Bonus * Barracks Bonus * Quick Feet * Attack Type * War * NW Mod * Ritual Bonus

• Note: War Attack Speed phases in to -15%, after 12 hours of War have passed.
• There is a net worth value adjustment for attack times. This adjustment compares your net worth to the net worth of the province you are planning to attack. If these are close to each other the base attack times as given below are used. If the net worth differs, then the base attack time is multiplied, so your attack time is longer. This does not affect intra-KD attacks or in War.

Base Attack Time

The base attack time is 14 hours. This is the value all calculations are based upon.

Minimum Offense to Win

To guarantee a win, you must send Mod Offense that is at least 1 greater than the defender's Mod Defense.

On Conquest attacks, the minimum Offense to win is 51% of the opponents Defense.

Attack Gains

For Attacks that target and capture Resources (Traditional March, Conquest, Plunder, Learn), the Gains are calculated as follows:

Gains = Target Resource * Attack Type * RPNW * RKNW * Multi-Attack Protection * Race Modifier * Personality Modifier * Castles Protection * Relations Modifier * Stance Modifier * Siege Science * Emerald Dragon * Attack Time Adjustment Factor * Ritual Bonus * Anonymity * Mist

• Resources are defined as: Land, Gold Coins, Food, Runes, Science Books
• Land attacks (except Ambush) also reward Military Credits (target's Defense Points *.008 * relative NW * Military Credits mod) and Building Credits (Acres captured * 0.4 * relative NW * Building Credits mod).
• Raze ignores all modifiers except Relations, Multi-Attack Protection and the Attack Time Adjustment Factor.
• Massacre ignores most Resource Gains modifiers, except RPNW, RKNW, Relations, Multi-Attack Protection and the Attack Time Adjustment Factor; Massacre is affected by Massacre Damage mod.
• Ambush ignores all modifiers except increased/decreased Ambush Battle Losses mod.

Province Networth Factor

Relative Province Networth (rpnw) = Targets Networth / Self Networth
Province Networth Factor = DEPEND ( rpnw ) :
rpnw < 0.567 = 0
0.567 < rpnw < 0.9 = 3 * rpnw - 1.7
0.9 < rpnw < 1.1 = 1
1.1 < rpnw < 1.6 = -2 * rpnw + 3.2
rpnw > 1.6 = 0

Kingdom Networth Factor

Relative Kingdom Networth (rknw) = Target Kingdom Average Prov. Networth / Self Kingdom Average Prov. Networth
Kingdom Networth Factor = DEPEND ( rknw ) :
rknw < 0.5 = 0.8
0.5 < rknw < 0.9 = rknw / 2 + 0.55
rknw > 0.9 = 1

NOTE: RKNW is based on the Average Province size of the Kingdom.
NOTE: RKNW factor protection slightly increased in Age 112.

Attack Time Adjustment Factor

Adding or subtracting hours modifies the Gains (based on your Attack Time), as follows:

Attack Type

Traditional March

Base gains are 12% and are capped at 20% of your Acres or your opponent's Acres, whichever is smaller.

Ambush

Will return 50% of the Acres lost in the attack. Unaffected by Gains modifiers. Inflicts 15% increased Military Casualties.

Plunder

Base gains are 50% gold, 60% food and 60% runes. Max gains is 1.75x base (67.5% gold, 81% runes/food). Military Casualties on Plunder defense are reduced by 50%.

Learn

Steals ~2.5% ^{Age 111} of target's allocated Books. Out of War Learns will no longer capture unallocated books at a greater rate. ^{Age 110}
During War, Learn temporarily removes ~35% ^{Age 109} of total allocated Science Books, these return over 48 Ticks.
Military Casualties on Learn defense are reduced by 50%, except during war. ^{Age 114}

Raze

Destroys a portion (~5%) of the target's Land. In War, this attack only destroys ~30% Buildings.

Conquest

Base gains are 6.8% land for a full hit, Gains are decreased in proportion to the relative Offense sent vs. target's Defense.
Available only within 5% Net Worth range outside Hostile/War, unless attacker has access to Enhanced Conquest.

Massacre

Base gains are 9.5% peasants, 7.5% Thieves and 5% Wizards. Efficiency increased roughly 2x during War. ^{Age 114}

Defending

Raw Defense = (Defense Specs * Def Spec Points) + (Elites at Home * Elite's Defense) + (Soldiers * Sold Def Points * Aggression) + Townwatch
Mod Defense = MAX ( Raw Defense * Defensive Military Efficiency , Land )

Minimum Defense

All land is protected by a minimum of 1 defense per Acre.
Opponent needs one offense to break your defense
This does not apply to Intra-Kingdom attacks.

Military Casualties

Base Military Casualties are 6.5%-8.5% on Offense, 5%-6.5% on Defense.

Changelog

  • +25% gains on Learn Attacks (as in genesis)

Age 43

• Attacks
  • Raze now destroys acres in war, too - razes after 200 acres do nothing in war

Age 44

• Attacks
  • Raze destroys all acres in war

Age 54

• Failed attacks have a chance to move the meter 1 point proportional to the amount of offense sent. An attack that fails by sending 70% of the offense required to break has a 70% chance to move the meter 1 point.
• Plunder, Learn, Massacre and Raze are now worth 2 points on the meter

Age 55

• The reduced gains protection afforded to smaller kingdom when attacked by larger kingdoms will be removed when the smaller kingdom reaches 50 points on the meter.
• Intra kingdom hits will remove some honor from the attacked province.
• Attacks in war will not take extra acres from the exploration pool.

Age 57

• In War the minimum gains will be reduced by 50%
• Players will be able to choose to extend or reduce their attack times to allow greater schedule flexibility.
