d100 tests, raw damage, and full attack/engagement resolution against the codified corpus. Load a campaign preset or a Builder-made character — the same entity everywhere — and hover any talent or trait for its rulebook text (verbatim locally, citation on the public site).
Focus Power tests per Chapter VI: pick a psyker (roster or Builder-made), a power and its difficulty, choose how much psy rating to commit — or push past it — and manifest. Doubles (or anything but doubles when pushing) roll Psychic Phenomena, 75+ chains into Perils of the Warp, opposed powers roll the target's resist through the same rules, and the Force weapon rider is one click.
Create a new Acolyte with the guided RAW flow, right in the sheet: origin → characteristics (rolled or manual) → wounds & fate → divination → starting XP → equipment. Every step stays editable — change your home world later and everything downstream re-derives, purchases repricing automatically. Spend XP at true rulebook costs with aptitude-match colour bands and rank pips; buy elite advances (their instant changes and unlocked talents apply themselves); specialist picks come from the rulebook's own specialization sets (Weapon Training's twelve groups, extensible in the DSL). Prerequisite-locked rows need the logged GM override; every acquisition — purchase, origin grant, elite-advance grant, trait, override — lands in one source-noted XP ledger.
The campaign roster and your custom Acolytes (★) on a Foundry-style sheet — characteristics, skills with engine-computed targets, talents, gear, the works. Edits propagate to the Roll and Builder pages automatically.
The built-in talents & weapon qualities, plus your own custom DSL rules — add, edit,
validate, toggle. The DSL also authors spec_list specialization sets (add a new
weapon group and the Builder's dropdowns pick it up).
