Negative morality increased the value of the leadership skill. Cyclops – increased the value of the ranged attack skill. An uncounterable berserker – increased the value of the fire magic skill. And there’s no need to even talk about resistance. And so on. This is what real diversity is. Not the rigid standard of “earth/air/logistics/offense/defense/wisdom/tactics,” where if anything else is present, the hero is considered subpar.
