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.
The formula for acres lost depends on "range", or the target's size relative to the attacker.
If target range is less than 55%:
(3.04 * (range^2) - 0.227 * range + 0.048) * AttackerSize
Otherwise, if target range is less than 75%:
(0.154 * range - 0.069) * AttackerSize
If target range is 75% or higher:
(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%.
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.
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.
