Written By King Nobert - A herd of cattle can move as slow as the slowest cow but when the herd is hunted, it is the slowest and calmed ones at the back that are killed first. This is because the smart and vigilant ones would flee from the danger. This type of attack is good for the herd as a whole because the general speed and health of the whole group keeps improving by the attrition of the few calmed and carefree members.
