Foundry VTT Dice & Rolls

About

The fvtt-dice-rolls skill provides expert guidance on the Foundry VTT Roll API, enabling developers to build robust game mechanics within the VTT environment. It covers the entire lifecycle of a roll—from constructing complex formulas with variable substitution to asynchronous evaluation and rendering results in chat. The skill includes best practices for actor/item data preparation via getRollData(), handling advanced modifiers like advantage/disadvantage, and implementing custom dice types to support diverse tabletop RPG systems.
