A roll button will be automatically added to D&D Beyond’s character sheet sidebars (abilities, skill checks, saving throws, weapon attacks, spells, class features, and more) that lets you either roll the dice directly into the VTT chat, or display the spell card, feature or equipment item for others to see. It also has an integrated dice roller for those who do not use a VTT, and rolls can also be sent to Discord.
Head over to the Screenshots page to see it in action.
Seriously, what more can you ask for? :-)
