D&D Dice Roller
Dungeons & Dragons runs on the d20: attack rolls, ability checks and saving throws all roll one and add a modifier. The d4, d6, d8, d10 and d12 roll damage, and the d100 covers percentile tables. Type d20a or d20d to roll twice and keep the higher or the lower, for advantage or disadvantage.
