Core Mechanic	Each Hero picks a single Proficiency number from 2 to 5. MIGHT actions (physical, martial) count d6 results equal to or under that number as Successes; MIND actions (mental, complex) count results equal to or over it. Roll 1d6 by default and add bonus dice for being Skilled, Prepared, Helped, or carrying the right Item. Rolling the Proficiency number exactly on a successful check earns a Hero Point, spendable for extra dice, rerolls, +1 damage, or a true in-world answer from the GM. Only players ever roll — enemy attacks resolve as automatic player Reaction Checks against the same Proficiency, with Block (1 less damage) or Dodge (no damage) chosen by the defender.	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.

Best For	Groups who want a complete heroic fantasy game they can start playing the same night — everything from character creation to campaign play fits in a twelve-page zine, with classic fantasy races and class archetypes already built in.	Groups who want heroic fantasy adventures with tactical grid combat, deep character customization, and access to more published adventures and supplements than any other RPG.
Highlights	A single Proficiency number from 2 to 5 defines a character's physical-versus-mental lean in one decision — high favors MIGHT (roll under), low favors MIND (roll over) — so building a Hero is a thirty-second commitment rather than a stat-by-stat exercise. Only players roll dice, even on defense: every enemy attack triggers an automatic Reaction Check from the targeted Hero, so the GM is free to narrate threats while every die at the table belongs to a player. Encounter Levels are calculated as Size × Actions × Challenge plus armor and shield bonuses, then summed across the party, giving the GM an at-a-glance balance number to scale opposition without writing statblocks.	Advantage/disadvantage system simplifies most situational modifiers to a single mechanic. Extensive class and subclass options across 12 base classes with 48 subclasses in the 2024 PHB. The largest third-party content ecosystem in tabletop RPGs. Free basic rules and starter sets lower the barrier to entry.
Considerations	Magic is limited to six Arcane and six Holy spells that Wizards and Clerics know in full from creation, with no spell progression, new spells, or list customization across a campaign. Damage caps at 2 points per hit and Stamina maxes at the Proficiency number plus armor, so combats resolve in a few rounds without granular HP attrition or extended tactical play. Character advancement between adventures is limited to gold rewards and a +1 starting Hero Points carryover — there are no levels, experience tracks, or stat increases that meaningfully change a Hero over the course of a campaign.	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.
