Invading

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

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

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

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
1500	10	26	54	69	91	120	139	186	308
2000	10	35	73	92	121	160	185	249	411
2500	10	43	91	115	151	200	231	311	514
3000	13	52	109	138	182	240	278	373	617
3500	15	61	127	161	212	280	324	436	720
4000	17	70	146	184	243	320	370	498	823
4500	19	78	164	208	273	360	417	560	926
5000	21	87	182	231	303	400	463	623	1029
5500	24	96	201	254	334	440	509	685	1132
6000	26	105	219	277	364	480	556	747	1235

Formula

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

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

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

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

See Teching for more information.

Bottom feeding

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

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.
