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:
      Total Acres * 1.5
      
   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 usually gain prestige.

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.

This is the amount of land lost by the target. The attacker's total gain is the land conquered plus 76.47%. These bonus acres are generated by the game and are not taken from any player. Thus, invasion is not a zero-sum event.

	40%	60%	75%	85%	100%	120%	133%	166%	250%
500	10	10	20	26	34	45	52	70	116
1000	10	19	41	52	68	90	105	141	233
1500	10	29	62	78	103	136	157	211	349
2000	10	39	82	104	137	181	210	282	466
2500	12	49	103	131	172	226	262	353	583
3000	14	59	124	157	206	272	315	423	699
3500	17	69	145	183	240	317	367	494	816
4000	19	79	165	209	275	363	420	564	933
4500	22	89	186	235	309	408	472	635	1049
5000	24	99	207	262	344	453	525	706	1166
5500	27	109	227	288	378	499	577	776	1283
6000	29	119	248	314	413	544	630	847	1399

Formula

The formula for acres lost depends on "range", or the target's size relative to the attacker. You then multiply that by 1.7647 to get the amount of acres gained from a hit.

If target range is less than 55%:

0.85 * (3.04 * (range^2) - 0.227 * range + 0.048) * AttackerSize

Otherwise, if target range is less than 75%:

0.85 * (0.154 * range - 0.069) * AttackerSize

If target range is 75% or higher:

0.85 * (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. If one-way war, it is increased by 15%. 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.

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 15% (if OP is 85% 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.

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.
