The overall chance of obtaining items by killing several monsters or destroying several boxes can also be calculated. For multiple rolls, the overall chance to receive a drop naturally increases. However, this increase is not linear. The increase is determined by following the binomial distribution formula: | The overall chance of obtaining items by killing several monsters or destroying several boxes can also be calculated.
