- Implement character creation functions to handle adventurer setup. - Add validation for adventurer name and selection of starting items. - Introduce new items in sample content pack: Flint and Steel, Pouch, Wax Sealing Kit, and Backpack. - Create tests for character creation functionality to ensure valid options and error handling. ✨Feature: implement dice rolling mechanics and tests - Add functions for rolling various dice types (d3, d6, 2d6, d66) with validation. - Implement modifier application with clamping for roll results. - Create tests to verify correct behavior of dice rolling functions. ✨Feature: add table lookup functionality and tests - Implement table lookup and resolution logic for defined tables. - Support for modified ranges and fallback to nearest entries. - Create tests to ensure correct table entry resolution based on roll results.
