Well, for starters you could generate multiple 'normal' random
numbers, add them up, and then scale the result to fit your target
range - that gives you an approximately bell-shaped distribution,
with the prevention of critical failure streaks as a free gift.

To encourage streaks of critical successes, you could take the
original bell-distributed random value, multiply it by a factor > 1
and then clip the result to your target range. This moves the bulge
of the number distribution towards the high end of the value range,
making critical successes more and critical failures even less
likely.

...hmm, in a game with gods and belief systems, this would be a nice
way to reward truly pious players.
