Since this only applies to negative numbers, I believe this fix reverses the intended damage calculation. Currently negative defenses close to 0 have damage multipliers slightly greater than 1 [dmg*(2-(1-e))], while large negative defenses have damage multipliers closer to 2 [dmg*(2-e)].

I believe it should be like that. But because in the case of negative defense the fraction (100/(100 + NEGATIVE)) actually gets bigger, as the defense gets more negative, because the denominator approaches 0.
This actually makes damage taken to became negative, when defense is between -50 and -100.
