Invading is the act of one dominion sending military units to another dominion in another realm.

If the invading force's offensive power (OP) is greater than the defensive power (DP) of the targeted dominion, the invasion is successful.

Invading is a crucial part of playing as an Attacker and Converter.

How To[edit]

  1. Find and calculate your target's DP.
    1. The best way to do this is to find out the target's unit numbers and add up all the values of their defensive units then apply any known modifiers. Modifiers can include spells such as Ares Call and walls bonuses.
    2. Land defense is applied if the total defense from military is less the following formula:
      (10 * Total Acres) - 3300
    3. Apply modifiers to Land defense as you would Military defense.
  2. Go the Invade page.
  3. Select your target. Double check to make sure it's the right one!
  4. Input the amount of units you want to send.
  5. Click Invade.

Successful Invasion[edit]

If your invasion is successful, you will gain land and if your target is 75% as big as you are or greater, the land you gain will have a 50% discount for buildings and you gain prestige. All land arrives twelve ticks/hours after your invasion.

Land Gain[edit]

Below is a table which shows land conquered for invasions where the attacker is from 500 to 6000 acres and the target is from 40% to 250% the size of the attacker. The minimum amount of acres gained is always 10.

This is the amount of land lost by the target. The attacker's total gain is twice the land conquered. These bonus acres are generated by the game and are not taken from any player. Thus, invasion is not a zero-sum event.

Land Conquered Before Bonus Acres
40% 60% 75% 85% 100% 120% 133% 166% 250%
500 10 10 18 23 30 40 46 62 102
1000 10 17 36 46 60 80 92 124 205

6000 26 105 219 277 364 480 556 747 1235

Formula[edit]

The formula for acres lost depends on "range", or the target's size relative to the attacker. You then multiply the number you get from the formula by 2 to get the amount of acres gained from a hit.

If target range is less than 55%:

0.75 * (0.304 * (range^2) - 0.227 * range + 0.048) * AttackerSize

Otherwise, if target range is less than 75%:

0.75 * (0.154 * range - 0.069) * AttackerSize

If target range is 75% or higher:

0.75 * (0.129 * range - 0.048) * AttackerSize

The "AttackerSize" is typically the current land size of the attacker. However, this variable in the formula is modified during war. In a one-way war, it is increased by 10%. In mutual war, it is increased by 20%.

Razing[edit]

Sometimes players will intentionally send less OP than the target's DP to cause casualties for the target, to lower the target's DP and allow for another dominion to successfully invade or to just do damage. This is called razing.

Razes cause 0% damage at and below 80% of the required offense to break the target, rising linearly to full casualties just below the needed offense to successfully invade.

Bounce[edit]

A bounce is a failed invasion. It is distinct from razing in that they are unintentional, often due to the target increasing its DP or the attacker making an error when calculating the target's DP.

If you fail by 20% (if OP is 80% or less of the target's DP) or more, the defender does not lose any troops and you also lose prestige. This is also called overwhelmed.

Research Points[edit]

Research points (RP) can be gained during a successful invasion.

See Teching for more information.

Bottom feeding[edit]

This is the act of invading a dominion below your 75% (Elite Guard) range. Caution is advised when deciding to do this: you will not have the building discount or prestige from a regular hit, and the formula for invasions is also harsher, meaning you'll gain less acres. Races that are more likely to engage in this are Lycanthrope, Spirit, and Undead, due to the conversions they gain when attacking. Conversely, Dark Elves are disincentivised from doing this, due to their Spirit Warriors dying normally when doing so.

If you invade someone between 74.99% and 60%, your Prestige is unchanged. If you hit below 60%, you will lose Prestige.

Being Invaded[edit]

If you are successfully invaded you will lose 5% of your prestige instantly. Any conquered acres that are constructed or under construction will cause your Dominion to gain a discount on rebuilding those acres. This discount does not stack with the discount from invading another Dominion. For example if your Dominion is invaded and you lose 100 acres, and 50 of those acres were still barren and 20 were under construction you will gain a discount on your next 50 acres built from exploration, daily land bonus, or from destroying and rebuilding.
