| Core Mechanic | For skill checks, roll a d20 and add the two relevant Talents plus the applicable Education score. A total of 21 or higher succeeds. Before a non-damage d20 roll, Luck Points can add +1 each to its bonus. | Roll a d12 Feat Die plus d6 Success Dice equal to the relevant skill rating, then total them against a target number. Gandalf’s rune succeeds automatically, while the Eye counts as zero and causes automatic failure for Miserable heroes. Sixes on successful rolls grant superior results. |

| Best For | Groups who want a survival-focused science-fiction campaign where characters cross frozen ruins, manage limited equipment, and resolve fights on a tactical grid. | Groups who want Middle-earth campaigns where dangerous journeys and the struggle against corruption shape their heroes. |
| Highlights | Frost Points turn prolonged exposure to subzero conditions into resilience checks, so shelter and protective gear shape expeditions. The optional Tuning Session assigns Talent scores through a short character-memory scenario, tying early choices to the resulting build. Combat uses a 2-meter grid with optional Perks that award attack bonuses for flanking or high ground. | Journey roles give each hero responsibility for the company’s travel. Hope improves rolls while Shadow threatens heroes with lasting flaws. Fellowship phases provide recovery and personal undertakings between adventures. |
| Considerations | Exposure to subzero temperatures triggers a Resilience check every 20 minutes of real table time and failure costs one Frost Point. Broad equipment archetypes rely on the Dungeonteller to define the specific items characters encounter. Combat resolves each attack through opposed rolls before damage is rolled. | The core’s cultures and virtues tie character options closely to Middle-earth. Carried equipment can make injured or fatigued heroes Weary. Repeated corruption can force a hero to retire. |
