d20 + modifier vs. DC/AC with advantage/disadvantage. Adds expertise dice, combat maneuvers with exertion pool, and structured exploration/social systems.
Best For
5e players who want deeper character builds, meaningful exploration and social pillar mechanics, and combat maneuvers without changing the core d20 framework.
Highlights
Backwards-compatible with 5e adventures, much deeper exploration and social pillars, combat maneuvers for martial classes, rich origin system (heritage + culture + background + destiny)
Considerations
More complex than base 5e, some players find the extra systems overwhelming, Requires the separate Trials & Treasures book for GM tools and magic items while monsters are in the Monstrous Menagerie book.
