D&D 5e classes and subclasses in Onyx: hit points, proficiencies, features by level and spellcasting, from the Player’s Handbook, Tasha’s and other books.
Overview
Each class page in Onyx shows hit points, proficiencies, the level-by-level feature table, spellcasting where the class has it, and every subclass with its own features.
When to use it
Compare classes before you make a character, or open your class when you level up to see what you gain next. The Onyx character builder uses the same class data.
