To understand why we have to use rams when we attack will
take the following example:
- the attacker have 20.000 Imperians;
- the defender have 20.000 pretorians and roman wall at
level 20;
- the players have the same populations
(they do not have bonus for small population) +
(no bonus from any hero).
The result is that the player who attack do not destroy
neither 50% from defense:
Attacker
Troops 0 0 20000 0 0 0 0 0 0 0
Casualties 0 0 20000 0 0 0 0 0 0 0
Defender
Troops 0 20000 0 0 0 0 0 0 0 0
Casualties 0 9830 0 0 0 0 0 0 0 0
We will add 200 rams to the attacker and we will see
a grow with 30% at the defense destroyed:
Attacker
Troops 0 0 20000 0 0 0 200 0 0 0
Casualties 0 0 20000 0 0 0 200 0 0 0
Defender
Troops 0 20000 0 0 0 0 0 0 0 0
Casualties 0 12685 0 0 0 0 0 0 0 0
We will add another 300 rams and we see another grow with 80%
comparatively with first attack:
Attacker
Troops 0 0 20000 0 0 0 500 0 0 0
Casualties 0 0 20000 0 0 0 500 0 0 0
Defender
Troops 0 20000 0 0 0 0 0 0 0 0
Casualties 0 18615 0 0 0 0 0 0 0 0
We will add another 200 rams to the attacker:
Attacker
Troops 0 0 20000 0 0 0 700 0 0 0
Casualties 0 0 18816 0 0 0 659 0 0 0
Defender
Troops 0 20000 0 0 0 0 0 0 0 0
Casualties 0 20000 0 0 0 0 0 0 0 0
We observe that the attacker will destroy all army and will
remain with army if he attacks with only 700 rams who are
be ready in only 5 days. A grow with over 100% at efficiency.
You will say that 700 rams eat a lot of crop and there could
be put other army in his place.
We will make the next simulation :
we change the 700 rams (2100 crop consuming) with 2100
Imperian (2100 crop consuming).
Attacker
Troops 0 0 22100 0 0 0 0 0 0 0
Casualties 0 0 22100 0 0 0 0 0 0 0
Defender
Troops 0 20000 0 0 0 0 0 0 0 0
Casualties 0 11284 0 0 0 0 0 0 0 0
The result is very weak comparatively with what we win
if we use rams.
