Now if you fight a legion with 251 remaining health, it leaves exactly 1 remaining health point! However, this legion splinter must still be attacked with many villagers in order to have a 100% chance of victory (see also: [[Combat Probability of Victory|Probability of Victory]]). This is absolutely inefficient and means a huge waste of attack resources!
Remember that the main reason for attacking legions is for the resistance points (RP) earned. The number of RPs earned depends on the health removed from the legion by the attack. Removing health points gives RP equal to the health points plus a factor of 1 to 1.25. 35 (max. 20% resistance bonus + max. 15% guild bonus). Example: 200 health points gives a maximum of 250 270 RP - as long as there is no bonus weekend.) So removing the last 1 health point gives 1 RP for this attack.
But the loss of strength and resources (durability of weapons, shields and helmets) is just as high as against a legion with maximum health.

In some cases some players want a legion not being defeated and come through to reach their village. (eg. when achieved resistance level 10 and want to gather the rewards for reaching the resistance levels again). Since there is still no 'flag' implemented where a village can tell other players NOT to hit legions of this village there is a common practice (just working with resistance level 10):
If you see a legion with full health (2,300) that legion should NOT be attacked.
