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.Make a D20 Test by rolling d20, adding relevant modifiers, and comparing the total to a target number. Ability checks, saving throws, and attack rolls use this procedure. Advantage and disadvantage use two d20s and keep the higher or lower result.

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 with configurable tactical combat, broad character options, and campaigns that span multiple levels.
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 resolve common situational effects by selecting the higher or lower of two d20 rolls. Backgrounds, classes, subclasses, and feats distribute character choices across creation and advancement. Weapon Mastery gives qualifying weapon users distinct tactical effects without replacing the action economy.
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 playSpell preparation, spell slots, class features, and conditions create several interacting resources for players to track. High-level characters combine many spells and features, increasing adjudication work for the DM. Bastions add a separate downtime procedure for campaigns that use the stronghold rules.
