House Rule: Increased Severity of Critical Hits

On any Critical Hit, additional damage will include an additional die roll PLUS all damage modifiers that the character receives in a normal attack.

Example: A Fighter with STR 16 and a longsword causes 1d8+3 damage on a normal hit. On a Critical Hit, he would cause the normal 1d8+3 damage plus an additional 1d8+3 damage.
