Roll d20 + attack bonus against the target's ascending Armor Class. Saving throws use a d20 roll-over against category-specific target numbers. Ability checks are d20 roll-under. Character advancement uses class-based XP tables and hit dice.
Best For
Groups who want a free, simple B/X-style game that modernizes classic D&D with ascending AC and separate race and class while remaining compatible with decades of OSR adventures.
Highlights
Completely free PDF with at-cost print copies through Lulu, race and class are separate unlike B/X source material, highly compatible with classic B/X and OSR modules
Considerations
Four core classes only (Cleric, Fighter, Magic-User, Thief) without supplements, racial class restrictions limit some combinations, no built-in setting or campaign framework
