Core MechanicRoll 2d6 + trait (6 stats from -3 to +3): 6- is a miss, 7-9 is a partial success, 10+ is a full success. Advantage and disadvantage add or remove a die (up to 4d6 total), keeping the best or worst two. Confidence upgrades 1s to 6s; desperation downgrades 6s to 1s. Channeler playbooks pilot Astirs using the CHANNEL trait for magic-related moves, while support playbooks contribute through B-Plots and Carrier upgrades.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 PbtA-style mecha action framed as rebellion against oppressive authority, with equal emphasis on dramatic relationships and cockpit combat.Groups who want heroic fantasy with configurable tactical combat, broad character options, and campaigns that span multiple levels.
HighlightsSplits playbooks into Channeler (mech pilot) and Support roles so non-pilots are mechanically distinct rather than sidelined. Conflict Turns provide a structured large-scale warfare system layered on top of individual scenes. Four optional campaign settings provide ready-made factions, mission hooks, and example Astirs as starting points. Confidence/desperation mechanic adds dramatic stakes beyond standard PbtA outcomes.Advantage 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.
ConsiderationsGroups must collaboratively define their Authority, Cause, and Carrier before play begins, though four optional settings are included as starting points. Channeler and support playbook split means the party must coordinate roles during character creation. Rules for Astir construction and Conflict Turns add mechanical weight beyond typical PbtA games.Spell 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.
