Core MechanicRoll d20 under an aspect (Stone, Flux, Aether, or Hearth) to succeed on tests. Favor and hindrance work like advantage/disadvantage (roll 2d20, pick better or worse). Knights pilot Apparatus (mechs) with resource dice: Armor Die reduces damage, Damage Die deals it, and Nexus Die represents the bond with allies: rolling max on the Nexus Die triggers a powerful Nexus Surge but downgrades the die. Battles play out on a span-based battlefield with tactical positioning.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 ForGroups who want a fantasy mecha experience: knight pilots bonded to towering Apparatus through a shared Nexus, battling Oghdra horrors across the floating Fragments of a shattered world called Eskhara.Groups who want heroic fantasy combining tactical grid combat with deep character-build options, scaling from one-shots up through long multi-tier campaigns.
HighlightsFills a fantasy-mecha niche with detailed lore, 10 playable kin and 16 Apparatus frames offer character variety, Nexus Die creates risk-reward tension, span-based combat is tactical without requiring a grid, built on The Black Hack's proven coreAdvantage 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.
ConsiderationsTightly bound to the Eskhara setting: hard to use outside it, moderate complexity with many subsystems (conditions, augments, boons, arsenal points), requires investment to learn unique terminology, combat-focused sessions may overshadow exploration and social playHigh-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.
