roll_MdN

roll_MdN() - This efun rolls a bunch of dice to get a nice weighted medium.

int roll_MdN( int dice, int sides )

This efun simulates the rolling of `dice' dice, each with `sides' sides. It returns the sum of such a throw, which will be a weighted medium.

The value returned ranges from `dice' to `dice * sides', with `dice * ( sides + 1 ) / 2' as most frequent value.
