Beyond20 integrates the D&D Beyond Character Sheet seamlessly into Roll20, Foundry VTT, Astral Tabletop and Discord.
It can also provide a dice roller for rolling all your skills and attacks directly from the D&D Beyond character sheets or monster stat blocks.
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 Virtual TableTop chat, or display the spell card, feature or equipment item for others to see.
