How do you know how much food need for an attack in Evony?

The amount of food needed for an attack in Evony is determined by several factors, including:

1. The type of troop: Each type of troop has a different food consumption rate. For example, infantry consumes less food than cavalry, and cavalry consumes less food than siege units.

2. The number of troops: The more troops you send on an attack, the more food you will need.

3. The distance to the target: The farther away the target is, the more food you will need.

To calculate the exact amount of food needed, you can use the following formula:

Food cost = (number of troops x food consumption rate) x (distance to target / movement speed)

Here is an example:

* You are sending 100 infantry (with a food consumption rate of 1) on an attack to a target that is 100 tiles away.

* The movement speed of your infantry is 10 tiles per hour.

* Therefore, the food cost of this attack will be: 100 x 1 x (100 / 10) = 1000 food.
