| Core Mechanic | Roll d20 + modifier against a target DC (for ability checks and saving throws) or AC (for attacks). Meeting or exceeding the target succeeds. Advantage rolls 2d20 and takes the higher; disadvantage takes the lower, replacing most situational modifiers. | Action Resolution Check (ARC): roll the die set by your Exclusive Skill score (d4 at skill 1–2 up to d12 at skill 9–10); rolling at or under the skill adds that result while rolling over subtracts the difference. Add the governing Character Stat and your Morality Index, then beat a hidden GM threshold (ARCT) or an opponent's roll (ARCO), with ties going to the defender. Because the Morality Index feeds every check, how closely a character follows their chosen moral Path constantly raises or lowers all their rolls. |

| Best For | Groups who want heroic fantasy combining tactical grid combat with deep character-build options, scaling from one-shots up through long multi-tier campaigns. | Experienced GMs running morally grounded fantasy who want player choices to carry hidden mechanical weight, and tables that prefer immersion and information asymmetry over full rules transparency. |
| Highlights | Advantage and disadvantage collapse most situational modifiers into one mechanic: roll a second d20 and keep the higher or lower, so play rarely stops to total small bonuses. Each of the 12 classes offers four subclasses in the 2024 Player's Handbook, letting players reshape a class's role without multiclassing. Bounded accuracy keeps proficiency bonuses small, so low-level threats stay relevant in numbers and DCs read consistently across all tiers. | A character's Morality Index adds to every check, so holding to a chosen moral Path lifts all rolls while drifting from it imposes a growing penalty until the character returns, and the GM tracks the grid position in secret so players feel the swing without seeing its cause. Secret Sorcery, the arcane tradition, pairs one element word with one principle word from twelve Magic Circles to declare any effect the GM prices by scope, removing spell lists and preparation and pushing magic toward improvised problem-solving. Characters have no hit points, so damage lowers the relevant Character Stat, and a stat reduced to zero starts a countdown of stat-plus-level turns during which healing can still reverse it before death locks in. |
| Considerations | High-level play (tier 3–4) introduces significant spell interaction complexity and encounter balancing challenges for GMs. No official rules for non-fantasy genres. Three core books at $50 each represent a significant investment for the full rules. | The Keep Uneducated Paradigm places the morality grid, hidden thresholds, growth points, and State of Mind tracking entirely on the GM, a parallel bookkeeping load that grows with the party. Resting recovers only one or two stat points per day and any real activity reverses healing, while magical healing ages the character a week per point restored, forcing long downtime between fights. Social interaction has no mechanical subsystem and defaults to the player's own roleplaying, so persuasion, intimidation, and negotiation rely on the generic check rather than any dedicated social rules. |
