Compares 1 die to all others, if it's the lowest, it subtracts it from sum. Embedded if-else ensures only 1 effect happens. Needs check to make sure not double of lowest number so we have put +1 to each die we are comparing to (since we do not have a <= sign!). For example comparing if 2 < 2+1, the answer is yes, therefore it will modify set score and stop. All other numbers that are lower will not trigger the Stat score modification because we are using < not <=, so the result is the same.
