[QUOTE="garrowolf, post: 5914423, member: 31900"] I have one dice roll per action in my system. One dice roll covers everything from attack to damage and defense. What you do is set the damage instead of having a damage roll. Then your margin of success over the defense of the target adds to the base damage. All magic has an error range which varies based on how skilled you are with magic and other conditions. Rolling an error is an automatic failure. Errors are usually 1-4 at most and 1 at the least. The larger the error range the greater the negative effect of a 1 or you have additional kinds of backlash. Rolling a crit (18-20 depending on how well you are with magic) will increase your roll by +5 or you can spend the crit on a special effect. I wouldn't switch to a percentile dice. They are slower to calculate with and D20 covers the same dice probabilities. [/QUOTE]
