THIS PAGE describes a game mechanism - Guide:Ambush in utopia. It also aims to discuss the implications of this game mechanism & how others have utilized it. To discuss further implications or ask questions with regards to Guide:Ambush, be sure to check out the discussions page.

Why Ambush?

  1. To kill troops (especially if your target is an Orc with Elites in the army).
    1. Why? --> They have an insanely low defensive value elite.
    2. Why? --> Ambushes are 25% faster than normal attacks.
  2. To decrease your target's incoming land (especially if your target is a chain target).
  3. Because you're able to Ambush + Trad him and want to rub it in his face.

Notes About Ambush

  1. You can ambush each successful attack once. If you fail, too bad.
  2. You cannot ambush if your opponent used Anonymity or War Spoils.
  3. You cannot ambush a hit from a personality or race that has full ambush protection.
  4. If you successfully carry out an ambush you will recapture 50% of his captured land
  5. You ALWAYS ambush the most recent hit of the province you select UNLESS Anonymity or War Spoils were used.
    1. You will ambush the last successful hit that did not use Anonymity or War Spoils.
    2. You CAN ambush an ambush.

How to figure out how much offense to send

  1. Take an SoM
  2. Record the value of troops out in the SoM.
  3. Once you have obtained these numbers, use this formula:
Raw Offense Required = [(Target's Elites sent*Racial Elite Defense Value) + (Target's Offspecs Sent*Racial Defspec Value) + (Target's Soldiers sent*Racial Soldier Defense Value)] * 0.8

Remember, this is the RAW offense required - therefore, don't bother sending more than 1 general, they have no effect!


June 4th, YR5 call (XX:XX) invaded Kzagl (XX:XX) and captured 81 acres of land.
June 4th, YR5 I just been (XX:XX) invaded Kzagl (XX:XX) and captured 139 acres of land.
June 4th, YR5 piercing through (XX:XX) invaded Kzagl (XX:XX) and captured 131 acres of land.

Kzagl didn't take particularly kindly to these attacks, and thought it would be a good idea to ambush one of them, so he took a SoM of I just been, the largest hit against him, to see what troops had been sent out against him and whether it was a good idea to ambush.

SoM on I just been

** Army #2 (Back in 10:46 hours) **

Ogres: 4,424 (58,397 offense / 9,733 defense)

Captured Land: 139 Acres

On seeing the no specialists (goblins) and high amount of elites (ogres), Kzagl made the decision to get a few of his acres back

So, basically the target sent 4424 ogres (well, he sent a few more, but lost some in the attack) to attack Kzagl. If he had sent some soldiers or specialists (or both) you'd see them also in the SoM. Now we can calculate what is going to be required to successfully ambush.

Orc elites are great for attacking with, not so great for defending with. Because they only have 2 defense (note values change form age to age, this is an example only), that's what they defend with on an ambush.

Therefore, 4424 Elites * 2 Defense Value = 8,848

The defense will fight at 80% of its normal capacity.' So, we multiply that number by 0.8

8,848 * 0.8 = 7078.4

Now, this is another important bit, when we calculate how much offense we're going to send, we don't modify it in anyway. If you're using angel's military calculator to do it, make sure you use the RAW OFFENSE number.

If you are just sending (6/0) offensive specialists at the target, you would require:

7079/6 = 1,770 off specs (rounded up)

If you set your attack to Ambush on the war room then the game will accurately display the offence you are about to send.

You always ambush the last hit made against your province by your target as long as the armies are still marching home with captured land.

So if the paper had looked like this:

June 4th, YR5 I just been (XX:XX1) invaded Kzagl Elven Grave (XX:XX) and captured 139 acres of land.
June 4th, YR5 piercing through (XX:XX) invaded Kzagl Elven Grave (XX:XX) and captured 131 acres of land.
June 4th, YR5 I just been (XX:XX) invaded Kagl Elven Grave (XX:XX) and captured 25 acres of land.

You would have to ambush the hit for 25 acres before you could ambush the hit for 139 acres. You wouldn't necessarily have to be successful though and could send 1 soldier and 1 general, because once you've ambushed a hit by a province, you can't ambush that hit again, so the game moves onto the next hit.
