This tool allows you to quickly roll as many dice as you need, and it'll add up any bonuses to those rolls you may need as well. The total of the rolled dice will also be displayed, but only those of a specific color.
There are 6 colors in total, but should there be a demand for more I can definitely add more of them.
Need a custom dice? Simply enter a custom numerical value in the 'cst' field, and once you hit the corresponding 'roll dice' button it'll automatically use that value for the results.
