If a predator or barbarian attacks a stack of subdued animals, all the subdued animals in the stack will be lost.Well what happens if you amass them?
Some of them may actually have strength or be fast or have some other features, that makes easier to explore.
Can subdued lion or elephant be killed by predator animals?
Or you can amass stack of 10 or 20 units.
All subdued animals have 0 strength and 1 movement point.
