This is a tool I use to help me while I play DnD. To use: Click the + or - under each Dice Type to add one of that type. It will display how much of each dice you have. If you want to add a custom Modifier/Amount, press the corresponding button and enter the amount. When you are ready, press the roll all button to roll. I also made it so that you can stack rolls. Press the green flag or reset button to reset.
